Advanced Baseball Metrics: Unlocking Deeper Player Insight
In recent years, advanced metrics have transformed the way we evaluate baseball players. One metric that has garnered significant attention is "Expected Home Runs" (xHR). This metric estimates the number of home runs a player would be expected to hit based on the quality of their batted balls. By considering factors such as exit velocity, launch angle, and batted ball distance, xHR offers a comprehensive assessment of a hitter's power potential.Another noteworthy innovation in baseball analytics is the "Avg. Swing Angle," which measures the average angle at which a player swings the bat. This metric sheds light on a player's approach at the plate, revealing tendencies to swing up or down on pitches. Understanding a player's Avg. Swing Angle can be invaluable in evaluating their ability to make contact and generate power.
Together, these metrics provide deeper insights into player performance beyond traditional statistics, enabling teams and analysts to make more informed decisions when it comes to talent evaluation and game strategy.

Now that we've established a fundamental understanding of this new data, what practical applications can we explore with it?
The above scatter plot showcases every MLB player who has taken at least 200 swings. The x-axis represents the player's average bat speed, while the y-axis indicates the player's expected weighted on-base average (xwOBA). The color of each point varies to reflect the player's average exit velocity. This visualization highlights a slight correlation between xwOBA and bat speed, but it distinctly shows a stronger relationship between bat speed and average exit velocity.
This scatter plot provides an insightful analysis by mapping out MLB players' performance metrics based on their swing data. By setting the x-value as the average bat speed and the y-value as their expected weighted on-base-average, with colors indicating exit velocity, we can observe trends in player efficiency. The findings suggest a modest link between xwOBA and bat speed; however, there is a clear connection between faster bats and higher exit velocities.
In essence, this detailed scatter plot demonstrates that while there is some association between xwOBA and bat speed among players with more than 200 swings, it's evident that increased bat speeds correlate more significantly with higher average exit velocities.
Swing Length, xwOBA, and a Multitude of Factors
The analysis of the relationship between swing length and expected weighted on-base average (xwOBA) reveals intriguing insights. Notably, this relationship is not linear; some players with long swings maintain high xwOBA, while others with shorter swings have low xwOBA. This complexity highlights that additional factors—such as bat speed and swing mechanics—significantly influence a player's xwOBA. Furthermore, it’s important to consider that the data used in this graph pertains to only one season. This temporal limitation suggests that the observed trends might shift over time as players adapt their swings and as the game itself evolves. Therefore, a multi-season analysis would be beneficial for drawing more comprehensive conclusions about these dynamics.
This instance highlights how a shorter swing length can lead to more frequent contact with the ball. Although the quality of these contacts isn't always exceptional, players positioned towards the upper right corner of the graph tend to connect more often and exhibit shorter swings. The scattered distribution of colored points indicates that we still haven't pinpointed a definitive link between success and these new bat-tracking statistics.
Bat-tracking technology provides a detailed analysis of how a hitter approaches each at-bat. It allows us to observe nuances in their strategy, such as adjustments made when facing a two-strike count or tendencies to favor pulling the ball.}
{With bat-tracking data, we gain clearer insights into a hitter's behavior during an at-bat. This includes identifying strategic changes in their swing under different counts and determining if they have a preference for hitting towards specific areas of the field.
This scatter plot showcasing average bat speed and swing length draws attention to five standout players: Isaac Paredes, Jeimer Candelario, Jose Altuve, Nolan Arenado, and Marcus Semien. What unites these athletes is their exceptional tendency to pull the ball significantly more than the league average. Leading this pack is Altuve with a remarkable 60.7% pull rate among qualified hitters.
All of these players rank within the top 25 in Pull% except for Semien. However, it's important to note that since 2022, Semien has climbed up to 13th place in Pull%. When we examine the broader context, a different narrative emerges altogether.
These are the leading hitters in baseball who favor pulling the ball, along with five other prominent hitters we previously highlighted. Upon examining their performance, we notice that there isn't a strong trend emerging just yet. This lack of clarity could be attributed to the early stage of the season; as more games are played, patterns will likely become more evident. However, one thing stands out: all these hitters, except for Spencer Torkelson, have swing lengths that exceed the average.
It's important to note that surpassing the red line indicates an above-average bat speed. Therefore, another conclusion can be drawn: longer swing lengths generally correlate with an increased number of pulled balls.
We can observe that hitters who favor pulling the ball and employ long swings tend to have higher success rates in terms of expected weighted On-Base Average (xwOBA). This finding aligns with the well-documented trend that a higher pull rate often correlates with greater success, so this graph's outcomes should not come as a surprise. The overall average xwOBA for these players stands at .328.
Players positioned in the bottom right quadrant exhibit a shorter-than-average swing length paired with a faster-than-average swing speed. Intuitively, this combination seems advantageous—reaching the ball more swiftly and with greater force. But does this theory hold water?
To investigate, I conducted a search for players whose swings measure 7.4 feet or less, coupled with a bat speed of at least 73 MPH. This analysis revealed that there are 11 such players.
Apart from Alvarez and Burger, every player in this lineup boasts an above-average xwOBA as of today. Collectively, this group averages an impressive .365 xwOBA! This figure is significantly higher than that of the previous cohort. Once again, this outcome was anticipated. Players who depend on where they hit the ball rather than their swing mechanics are often more susceptible to inconsistencies.
If a longer swing generates a higher average exit velocity but also increases the risk of poorer performance, what does this mean for players with exceptional bat speed but elongated swing paths? There are seven players who each have taken at least 200 swings and possess a swing length of 7.8 feet or more, along with an average bat speed of at least 74 MPH.
Improving Plate Discipline: A Key to Walker′s Potential
Jordan Walker has recently faced some struggles, yet he remains a player with elite raw power. Encouragingly, Walker has shown signs of improvement in his plate discipline, successfully reducing his strikeout rate to 20.0% since being demoted to AAA. This adjustment could be pivotal for his development and future contributions.On the other hand, while many power hitters have the ability to hit impressive home run totals, their high strikeout rates can make them somewhat boom-or-bust options. This inconsistency potentially limits their overall impact on the game despite their undeniable power at the plate.
A longer swing generally increases the likelihood of a missed hit, even if the bat reaches higher speeds. In summary, players in the 'Top Right' category average an xwOBA of .347.
The final group to take the spotlight is led by none other than Luis Arraez, who stands out as a significant anomaly in the world of bat-tracking. Unlike their peers, these players may not excel in generating high bat speed, but they excel at making consistent contact with the ball.
Identifying the Dead Zone to Enhance Hitter Performance
The scatter plot analysis highlights that the performance metrics for hitters are clustered within a narrower spectrum, making it challenging to pinpoint outliers. This concentration suggests that most hitters exhibit similar levels of production, thereby reducing variability.Moreover, an important observation is the identification of the 'dead zone' for hitters. This area, located in the bottom left quadrant of the graph, is characterized by low expected weighted On-Base Average (xwOBA) and low exit velocities. Hitters falling into this quadrant typically struggle with both contact quality and overall batting effectiveness, indicating a critical area for potential improvement or strategic adjustment.
Overall, understanding these data patterns allows coaches and analysts to better evaluate player performance and identify areas needing enhancement. By focusing on players who consistently land in this 'dead zone,' teams can develop targeted interventions aimed at boosting their offensive contributions.
Utilizing the robust capabilities of Baseball Savant's search engine coupled with Python's Pandas for data analysis, I meticulously sifted through a multitude of files. My aim? To pinpoint which big league players exhibit the most significant changes in their approach when they're either leading or trailing in the count. Let's begin by examining the more cautious hitters. Below, you'll find the players who show the greatest reduction in bat speed when they are at a disadvantage in the count.
First on our list are those who adopt a more conservative strategy. These athletes noticeably slow down their bat speed when they fall behind, showcasing a distinct shift in their offensive tactics under pressure.
Prominent figures in the field include Luis Robert Jr., Xander Bogaerts, and Seiya Suzuki. Among them, Luis Robert Jr. showcases the most significant disparity between his A swing and B swing.
It appears that Robert Jr. employs three distinct batting styles. Although we are examining a limited sample size of roughly 30 plate appearances, there is evident effort in altering his approach. This observation might change as we gather more comprehensive data from Southside's centerfielder, but it remains an aspect worth monitoring closely. Expanding the parameters to include a larger sample size yields the following list:
Currently, Harold Ramirez stands as the undisputed master of adjusting his strategy when facing two strikes. Close on his heels are Bader, Herrera, and Conforto. To give you a visual understanding, let's examine their swing distribution charts stacked one atop another:
Strategic Adjustments Impact Hitter Performance in Two-Strike Situations
In recent analyses of player performance, it has been observed that in two-strike situations, certain hitters experience a notable drop in bat speed. For instance, Conforto's decrease in bat speed is particularly evident during these scenarios, showcasing a distinct valley in his distribution. Similarly, Shohei Ohtani, one of the most prominent hitters today, also exhibits a significant decline in bat speed when confronted with two strikes.This observation aligns with broader trends seen among players who adjust their approach based on the count. The average expected weighted On-Base Average (xwOBA) for this group of adaptive hitters stands at .322. This figure includes Ohtani and indicates that those who alter their tactics under pressure can achieve comparable levels of success to those maintaining consistent bat speeds throughout different counts.
These insights offer a deeper understanding of how strategic adjustments can impact performance metrics like xwOBA, emphasizing the nuanced approaches elite players employ to navigate challenging situations at the plate.
These athletes exhibit remarkable consistency when stepping up to the plate. The variance in average bat speed among the top contenders is truly astonishing. A mere 0.005 MPH shift in average bat speed during a two-strike count is indeed noteworthy. Let's delve into the distribution chart for the leading four hitters on this list:
Overall, the average xwOBA for the 20 smallest variations in swing speed is .315. This result is significantly closer than I had anticipated. However, a more detailed analysis at the individual player level could potentially reveal more pronounced differences rather than averaging out all data.
For a bit of fun, here’s a list of players whose bat speed actually increases when they face a two-strike count.
Miguel Sano stands out as the most intriguing player in this analysis. Not only does he possess the highest bat speed among all listed, but he also opts to ramp it up when facing potential strikeouts. This strategic adjustment adds a fascinating layer to his gameplay.
It's quite surprising to see Brice Turang included here. Known for his contact-hitting abilities since making his debut last season, Turang appears to gain an extra burst of bat speed when he's falling behind in the count.
Jose Siri's presence on this list raises some concerns regarding the average xwOBA figures for these players. Despite being a power-speed combination outfielder, Siri has struggled significantly with plate discipline over recent years.
The combined xwOBA for these 20 players stands at a mere .297. That's quite concerning. Honestly, it doesn't come as a shock to me.
In summary, the data we have is both fascinating and incredibly engaging. Having access to such information is remarkable, opening up unprecedented opportunities for in-depth baseball research.
Nevertheless, I don't believe the graph above holds significant importance. I would prefer to utilize this data to propose adjustments in the batting techniques of specific players like Jazz Chisholm Jr. or Jacob Young, both of whom find it challenging to modify their swing when they fall behind in the count. While it's certainly intriguing to explore and analyze this information, the x-y graph does not demonstrate a strong correlation with success, at least based on my observations.
