Baseball, the national pastime, is a sport rich in history and statistics. From
Babe Ruth’s home runs
to
Ty Cobb’s batting average
, iconic numbers dominate the conversation. Yet, there are underrated statistics that significantly impact the game yet often go unnoticed. Herein lies a
deep dive
into ten such statistics, elucidating their importance and relevance.
wRC+: Runs Created Above Average
A superior alternative to batting average, wRC+ measures a player’s total offensive production. By calculating runs created and comparing it to league average, it offers a more comprehensive assessment of offensive value.
xFIP: Expected Fielding Independent Pitching
xFIP, an ERA estimator, considers factors pitchers can control: walks, strikeouts, and home runs. Ignoring fielding and defense, it’s a valuable metric for evaluating a pitcher’s true talent.
BB%: Baseball-Reference’s Walk Rate
BB%, a metric measuring a batter’s walk rate, is crucial for assessing plate discipline. Higher values indicate an ability to draw more walks and avoid strikeouts, which can significantly impact a team’s offensive production.
GB%: Ground Ball Percentage
Understanding a player’s GB%, or ground ball percentage, is essential for evaluating their defensive positioning and park effects. Ground balls have a higher probability of resulting in outs than fly balls, influencing a player’s overall performance.
5. SIERRA: Skills-Based Integer Replacement Points Above Average
An advanced pitching metric, SIERRA measures a pitcher’s skill level. By evaluating a pitcher’s ability to generate swings and misses, it provides insights into their overall effectiveness and potential for success.
6. ISO: Isolated Power
ISO, a power metric, measures a player’s extra base hits per fly ball. It provides context for a player’s raw power, helping to separate true home run hitters from those with inflated numbers due to their park or playing position.
7. BABIP: Batting Average on Balls In Play
A vital metric for evaluating batting performance, BABIP measures the percentage of balls put in play that result in a hit. Deviations from league average can signify unsustainable performance or underlying skill.
8. UZR: Ultimate Zone Rating
A defensive metric, UZR, measures a player’s runs saved above average. By assigning values to different types of plays and positions, it offers an objective evaluation of a player’s defensive contributions.
9. OBP: On-Base Percentage
A vital offensive metric, OBP, measures a player’s ability to reach base. By combining walks and hits, it offers a more complete picture of a batter’s offensive value, providing context for batting averages and slugging percentages.
10. FIP-: Fielding Independent Pitching – Runs Allowed
An advanced pitching metric, FIP-, calculates a pitcher’s runs allowed above average. By subtracting their expected runs from the actual runs allowed, it offers insights into a pitcher’s true performance and potential for improvement.
By incorporating these underrated statistics into your baseball analysis, you’ll gain a more comprehensive understanding of the game and the players that make it great.
Unraveling Baseball’s Hidden Gems: A Deep Dive into Underrated Statistics
Baseball, a sport steeped in history and tradition, has long been influenced by
statistics
. From the early days of earned run averages (ERAs) and batting averages to the modern era of advanced metrics, numbers have played a pivotal role in shaping player evaluations, team strategies, and fan engagement. In the digital age, where
data
is more accessible than ever, statistical analysis in baseball has evolved at an unprecedented pace.
Player evaluation
and team strategy have seen a paradigm shift as new metrics provide insights into aspects of the game previously overlooked. However, despite this data revolution, some statistics
continue to fly under the radar. This article aims to shed light on these
underrated statistics
, whose significance in understanding baseball’s nuances is often underappreciated or not widely known.
Underrated Statistics
: A Closer Look at Baseball’s Hidden Gems
Run Expectancy
Although not a new concept, run expectancy
is gaining traction as a valuable tool for understanding a team’s offensive potential. Run expectancy measures the number of runs a team can be expected to score in a given situation based on historical data.
Wins Above Replacement (WAR)
Although widely known, the nuances of WAR and its different components such as Defensive WAR
and Base Running WAR
, often go unnoticed.
Exit Velocity
As a key metric in the sabermetric revolution, exit velocity is increasingly becoming important for evaluating hitters’ power potential.
Launch Angle
Alongside exit velocity, launch angle is critical for understanding a hitter’s power profile and their ability to drive the ball out of the yard.
5. Pitch Value
By evaluating the value of individual pitches, teams can better understand pitcher performance and adjust strategies accordingly.
6. Contact Percentage
This metric sheds light on a batter’s ability to make solid contact with the ball, providing insights into their offensive potential.
7. Pitch framing
Although not a new concept, the importance of pitch framing in affecting run expectancy and pitcher performance is often underappreciated.
8. Fielding Percentage
Though a basic statistic, fielding percentage remains underrated in evaluating defensive performance and its impact on overall team success.
9. Splits
Analyzing batter and pitcher splits against different opponents, situations, and pitch types can provide valuable insights for strategy development.
10. BABIP
Understanding a player’s batting average on balls in play (BABIP) is crucial for evaluating their true offensive potential and separating them from those benefitting from unsustainable luck.
Statistic #1: Wins Above Replacement Pitcher (WARP)
Wins Above Replacement Pitcher (WARP) is a sabermetric baseball statistic that measures the value of a pitcher in terms of the number of wins they contribute above a replacement level player. This metric goes beyond traditional statistics like Earned Run Average (ERA) and Wins, as it attempts to quantify a pitcher’s entire contribution to their team.
Description of WARP and its significance
The replacement level player is an abstract entity representing a hypothetical player with average performance. If a team’s actual pitcher performs better than this replacement level player, then they contribute positively to their team’s win total. WARP takes into account various factors like runs allowed, strikeouts, walks, and pitching workload. It also adjusts for defensive contributions and league context.
Comparing a player’s production to a replacement level player
By comparing a pitcher’s performance to a replacement level player, WARP allows us to evaluate their true value. For instance, a pitcher with a 4.00 ERA but a high number of strikeouts and few walks might have a positive WARP, indicating they are more valuable to their team than the average replacement player.
Adjusting for defensive contributions and league context
WARP also accounts for defensive contributions, which can significantly impact a pitcher’s performance. A pitcher with an excellent defense behind them will allow fewer runs and thus contribute more wins, even if their individual statistics are not particularly impressive.
Real-life examples of how WARP can provide new insights
Comparing pitchers with similar ERAs but different WARPs
Example 1: Consider two starting pitchers, Player A with a 3.50 ERA and Player B with a 3.80 ERWhile the difference in ERAs might seem significant, WARP may reveal that Player A only contributes 1 additional win compared to a replacement level player, while Player B contributes 4.5 wins. Based on this information, we can conclude that despite the lower ERA, Player A doesn’t provide as much value to their team compared to Player B.
Highlighting the value of relievers and starting pitchers in the playoffs
Example 2: During the baseball postseason, relief pitchers often receive significant attention due to their critical role in close games. However, WARP can help us understand that these relievers’ contributions might not always translate directly into wins or save opportunities. By analyzing a relief pitcher’s WARP, we can gain insight into their true impact on the team and their value in high-pressure situations.
I Statistic #2: Fielding Independent Pitching (FIP)
Fielding Independent Pitching, or FIP for short, is a
statistical pitching metric
that aims to measure a pitcher’s performance without considering the factors beyond his control, such as fielding or luck. FIP was developed by baseball statistician Tom Tango and his colleagues in 200It’s an essential tool for
evaluating pitchers
and can significantly influence
roster decisions and fan perception
.
Definition of FIP and its components:
FIP calculation is based on four core components: Home Runs allowed (HR), Base on Balls (BB), Strikeouts (K), Hitting-by-pitch (HBP), and Stolen Bases against (SB). The formula is as follows:
FIP = (HR * 1.3) + (BB * 3) – 2 * (K – BB) + 3 * (HBP / IP) + (SB * 0.7)
Where IP represents innings pitched. Each component is weighted based on its impact on a team’s run defense. Home runs, for instance, are given the highest weight factor since they contribute significantly to a pitcher’s Earned Run Average (ERA).
Real-life examples of how FIP can influence roster decisions and fan perception:
Identifying pitchers who outperformed their ERAs:
Consider a pitcher like Max Scherzer, who had an impressive 2019 season with a 2.92 ERA but a slightly higher FIP of 3.18. While his ERA was lower, it wasn’t an accurate reflection of his actual pitching performance. Scherzer’s FIP highlighted that his ERA might have been affected by his team’s strong defensive play or just plain luck. This information could help baseball decision-makers when evaluating Scherzer’s value and performance for potential trades, extensions, or contract negotiations.
Understanding the impact of a pitcher’s team defense on his statistics:
Conversely, FIP can help fans and analysts better understand the impact of a pitcher’s team defense on his statistics. For example, if a pitcher like Joe Ross had an ERA of 3.45 but a FIP of 4.61, fans and analysts might infer that his team’s strong defense played a significant role in suppressing his ERBy recognizing this disparity between his ERA and FIP, fans can gain new insights into the pitcher’s performance and appreciate the role of his teammates in his success.
Statistic #3: Run Expectancy (RE) and Run Value (RV)
In the realm of baseball statistics, two essential metrics that shed light on a team’s offensive productivity are Run Expectancy (RE) and Run Value (RV). To delve into the significance of these metrics, let’s first grasp the underlying concept of runs scored and expected runs.
Runs Scored and Expected Runs: The Foundation
A run is scored when a player advances around the bases and crosses home plate. However, not every situation results in the same number of runs being scored. For instance, having base runners on first and second with no outs presents a better opportunity for scoring runs than having a solo runner on third with two outs. This is where RE and RV come into play.
A.1 Understanding the Concept of Run Expectancy (RE)
Run Expectancy refers to the average number of runs a team is expected to score in a given situation. It takes into account various factors such as base runners, outs, and the league’s run environment (i.e., the average number of runs scored per inning).
A.2 Understanding the Concept of Run Value (RV)
Run Value, on the other hand, represents the actual number of runs produced by a specific player or team in a given situation. It is calculated by multiplying the RE with the outcome (runs scored).
Real-life Applications of Run Expectancy (RE) and Run Value (RV)
Assessing the Impact of a Hitter’s Clutch Performances
By analyzing RE and RV, we can evaluate the impact of a hitter’s performance in high-pressure situations. For example, if a player consistently drives in runs when men are on base and two outs (high RE situation), their value to the team is significantly greater than someone who only performs well with a base empty or minimal runners aboard.
Comparing the Run Production Between Teams or Lineups
Comparing RE and RV across different teams or lineups allows us to gain valuable insights into their offensive strengths and weaknesses. For instance, a team that consistently performs well in high-pressure situations (high RE) may have an edge over their opponents, potentially leading to more wins.
Statistic #4: BABIP (Batting Average on Balls In Play)
BABIP, or Batting Average on Balls In Play, is a crucial statistical measure in baseball analysis. This metric represents the percentage of balls that a player hits in fair play which result in base hits.
Significance of BABIP
Why is BABIP important?
Firstly, it helps in assessing a player’s true hitting ability. While batting average is a common performance indicator, it doesn’t differentiate between hits on balls put in play and those that result from walks or home runs. BABIP allows us to separate the two, enabling a more accurate evaluation of a player’s ability to turn batted balls into base hits.
Role of Luck and Variability in BABIP
However, it’s essential to understand that there is an inherent component of luck and variability in BABIP. A player with a high BABIP one season might regress towards the league average the next, or vice versa. This is because not every ball hit in play results in a base hit based on chance and the specific defensive positioning of the opposing team.
Real-life Applications of BABIP
Player Evaluation and Projection
BABIP plays a significant role in evaluating player performance and projecting future success. By
identifying players
who benefit or suffer from unsustainable BABIPs, we can gain insights into potential regression to the mean. A player with an unusually high BABIP might have had good fortune on their side in the previous season, and their production may normalize, while a player with a low BABIP may be due for an uptick.
Contextualizing Production
Moreover, it’s important to contextualize a player’s production based on league trends and team context. For instance, if the league average BABIP is high or low, this can impact individual player evaluations. Similarly, understanding how a team’s defense performs in terms of converting balls into outs and how it affects a particular player’s BABIP can provide valuable insights.
VI. Statistic #5: Runs Created (RC) and Runs Created Plus (RCP+)
Runs Created (RC) is a baseball statistic that aims to measure a hitter’s overall offensive contribution towards the team in terms of runs scored. It was first introduced by baseball analyst Bill James in his 1982 Baseball Abstract. The RC statistic is calculated based on the number of runs a hitter is expected to produce given his total number of hits, home runs, walks, and stolen bases. However, RC has its limitations. Critics argue that it does not account for defensive factors or team context. For instance, a hitter who plays for a team with strong defensive players will have fewer runs scored than if he were on a weaker defensive team, even if his individual offensive performance remains the same. Additionally,RC does not consider the impact of ballpark factors, such as park homerun effects or wind conditions, on a hitter’s offensive production.
Introduction to RCP+ and its advantages over runs created
To address some of the limitations of RC, a more advanced version called Runs Created Plus (RCP+) was developed. RCP+ builds on the foundation of RC but adjusts for league context, ballpark factors, and defensive shifts. By doing so, it provides a more fair and accurate comparison of players’ offensive productivity across different teams and seasons. The league context adjustment takes into account the overall offensive environment of the league in which a player performs, while the ballpark factor adjustment compensates for the impact of various park conditions on run scoring. Lastly, the defensive shift adjustment accounts for the effects of opposing teams’ strategic decisions to position their fielders differently based on a hitter’s tendencies.
VI. Statistic #6: Weighted On-Base Average (wOBA) vs. On-base Percentage (OBP)
Weighted On-Base Average, or wOBA, is a sabermetric statistic that extends the conventional On-base Percentage (OBP) by giving more weight to extra-base hits and home runs, as these contribute significantly more to a team’s run production than singles. wOBA was first introduced by Tom Tango in 2006 as a means to better evaluate hitters’ offensive performances.
Evolution from OBP
The calculation of wOBA begins with a hitter’s OBP, which is simply the ratio of times reached base divided by at-bats. However, wOBA then assigns weights to different types of hits – singles (weight = 0.7), doubles (weight = 1.2), triples (weight = 1.6), and home runs (weight = 1.8) – based on their contribution to the team’s run total. For instance, a double with an OBP of 0.35 would be given a weight of 1.2 * 0.35 = 0.42. By incorporating these weights, wOBA provides a more accurate representation of a hitter’s offensive contribution than OBP alone.
Comparison to Traditional Offensive Stats
Compared to traditional offensive stats like batting average or RBIs, wOBA offers a more holistic perspective on hitters’ performances. For example, consider two players with identical OBPs (e.g., 0.35). Player A may have a higher batting average but accumulate most of his hits as singles, while Player B might have fewer singles and more extra-base hits. By examining their wOBAs, we can determine that despite similar OBPs, Player B’s offensive value is greater due to the increased run potential from his extra-base hits.
Real-life Examples
wOBA can significantly enhance our understanding of hitters’ performances in various contexts. For instance, when evaluating the offensive value of platoon players or late-inning pinch hitters, wOBA offers a more accurate representation of their impact on the game, as these players often have limited at-bats. Additionally, comparing players with similar OBPs but different wOBAs can reveal subtler nuances in their offensive performances.
VI Statistic #7:
Defensive Runs Saved (DRS) and Ultimate Zone Rating (UZR) are two advanced defensive metrics that have gained significant popularity in baseball analysis. These stats aim to
measure a player’s contributions to preventing runs
through their defensive actions. It’s essential to note that these metrics are not just about highlighting the number of plays made, but rather focusing on
the value and impact
of those plays.
Overview of DRS and UZR as advanced defensive metrics:
Both DRS and UZR take into account various factors like position, park factors, and team context. These advanced metrics help provide a more nuanced understanding of a player’s defensive impact compared to traditional stats such as fielding percentage or assists.
Measuring a player’s contributions to preventing runs:
Both DRS and UZR utilize the concept of “runs saved” to evaluate defensive performance. By estimating how many runs a player has prevented defensively compared to an average player at their position, these metrics offer valuable insights into a player’s defensive contributions.
Adjusting for position, park factors, and team context:
One of the significant advantages of DRS and UZR is their ability to
account for positional differences
. For instance, a defensive shortstop’s range and skills might be different from those of a first baseman. These advanced metrics acknowledge these differences and adjust accordingly to provide more accurate evaluations. Additionally, they consider park factors and team context to ensure that the results are as unbiased and informative as possible.
Real-life applications of DRS and UZR in evaluating defensive impact on a team:
Understanding the implications of DRS and UZR goes beyond just analyzing individual player performance. Here are some real-life applications of these metrics:
Identifying undervalued defenders and overvalued hitters:
By using DRS and UZR, teams can uncover overlooked defensive gems. These metrics might reveal that a seemingly average hitter is an excellent defender, making him more valuable to the team than initially thought. Conversely, they can also highlight overvalued hitters whose defensive shortcomings negatively impact their overall worth.
Understanding the importance of defense in close games and high-leverage situations:
In baseball, every run matters, especially when it comes to
close games and high-leverage situations
. Advanced defensive metrics like DRS and UZR help demonstrate how valuable a strong defense can be. These stats provide insights into which players excel in these situations, allowing teams to make informed decisions and improve their defensive strategies.
IX. Statistic #8: Win Shares (WS)
Win Shares (WS), a holistic player evaluation metric, is an innovative approach to measuring a player’s overall contribution to his team in terms of wins. Introduced by Baseball-Reference.com, WS is a valuable tool for understanding the impact of individual players on team success.
Description of WS
WS is calculated by assigning credits for the number of wins contributed by a player’s offense, defense, and position.
Offensive contribution
WS assigns credits based on a player’s offensive production compared to league averages, adjusting for league context and teammates.
Defensive contribution
WS uses a similar method for defensive contributions, assigning credits based on a player’s fielding and pitch framing abilities compared to league averages.
Position adjustment
WS recognizes that certain positions are more valuable than others, assigning position adjustments based on historical data and player responsibilities.
Real-life applications of WS
Comparing players within the same position or role: Win Shares provide a standardized metric to compare the relative value of different players. For instance, comparing two center fielders in terms of their WS totals helps determine which one has had a greater overall impact on their team’s success.
Understanding the impact of a player’s role
Team dynamics: Win Shares can also help in understanding the impact of a player’s role on his WS total. For example, a team may have two players with similar offensive numbers but different defensive responsibilities. The one with more defensive contributions (and therefore more WS) might be more valuable to the team, even if their batting statistics are comparable.
X. Statistic #9: FanGraphs’ Steamer and ZiPS Projections
FanGraphs‘ Steamer and ZiPS projection systems are invaluable tools for evaluating talent in the baseball world. These advanced statistical models use historical performance, contextual factors, and a player’s age to forecast their future production. By understanding the intricacies of these systems, we can gain insight into players’ future potential, identify prospects with high upside or significant downside risks, and make informed decisions when comparing projected performance between players or teams.
Introduction to FanGraphs’ Projection Systems
FanGraphs’ Steamer and ZiPS projections are two of the most widely used and trusted systems in baseball analysis. Both models utilize historical performance, contextual factors, and a player’s age to generate accurate forecasts for future production. While they share some similarities, it is essential to understand the unique components of each system.
Understanding the Components of Steamer and ZiPS Projections
Steamer: This projection system, developed by Sean Smith, is based on a player’s Statcast data, park-adjusted historical performance, and league-average aging curves. Steamer uses a regression analysis to estimate each player’s production in various offensive and defensive categories for the upcoming season. The system also takes into account contextual factors such as lineup position, team defense, and bullpen support.
ZiPS (Zestimate of Player Performance): Developed by Marcus Graham, ZiPS is another advanced projection system that uses a player’s historical performance, aging curves, and regression analysis to forecast future production. However, ZiPS also considers team context by using the projected performance of their teammates to influence individual player projections.
Real-life Applications of Steamer and ZiPS Projections
Identifying Prospects with High Upside or Significant Downside Risks
Using Steamer and ZiPS projections, analysts can identify prospects with high upside or significant downside risks. For example, a prospect with excellent historical performance but advanced age may show a greater decline in projected performance compared to their peers. Alternatively, young prospects with strong statistical profiles could demonstrate significant upside based on their projections.
Comparing Projected Performance Between Players or Teams
Steamer and ZiPS projections can also be used to compare projected performance between players or teams. For instance, comparing the offensive production of two first basemen can help determine which player is more valuable for a given fantasy baseball team or MLB organization. Similarly, projecting a team’s overall offensive performance using these systems can provide insights into their potential success for the upcoming season.
XI. Statistic #10: Pitch F/x Data and Sabermetrics’ Application to Pitching
Pitch F/x data, a technology developed by MLB Advanced Media, has revolutionized the way we analyze pitching performance in baseball. This innovative system uses high-speed cameras to track every pitch thrown in a game, providing an unprecedented amount of data for analysis. Pitch F/x data consists of several key components:
Location:
where the pitch is thrown relative to the strike zone,
Velocity:
the speed of the pitch at release point, and
Spin rate:
the rotation rate imparted on the ball. These data points, combined with others like break and horizontal movement, form the foundation for advanced pitching statistics.
Understanding the components of Pitch F/x data is crucial in evaluating pitchers and team strategies. For instance, location data helps identify pitchers with pinpoint control or those who struggle to hit their targets consistently. Pitchers like Mariano Rivera and Aroldis Chapman are renowned for their ability to place pitches precisely in the strike zone, thanks to their excellent location data. Conversely, struggling pitchers may exhibit inconsistent placement, leading teams to seek solutions.
Real-life applications of pitching statistics
Identifying pitchers with specific strengths or weaknesses:
By analyzing pitch usage and performance data, teams can determine the strengths and weaknesses of their own pitchers as well as those of their opponents. For example, a team might discover that one of their starting pitchers excels at generating swings and misses with his slider but struggles with commanding his fastball. Armed with this information, the team can adjust their strategy to capitalize on their pitcher’s strengths or address his weaknesses through targeted training.
Understanding the impact of pitch usage on team success:
Another application of sabermetric pitching analysis involves assessing the role of pitch usage patterns in team success. Research has shown that teams who use their pitches effectively, such as throwing more strikes and limiting walks, enjoy an edge over their opponents. Conversely, teams with inefficient pitching strategies may struggle to win consistently.
In conclusion, Pitch F/x data and sabermetrics‘ application to pitching has transformed the way baseball teams evaluate talent, build strategies, and make tactical decisions. By understanding the components of Pitch F/x data and applying advanced statistical analysis, teams can gain valuable insights into pitcher performance and ultimately improve their chances of success.
