Team Swing Decisions: An Analytical Overview of PLV Decision Value in MLB
This analysis explores the intricate world of swing decisions in Major League Baseball, leveraging Pitcher List's proprietary Decision Value (DV) metric. This advanced analytical tool assesses a hitter's effectiveness in choosing whether to swing at a pitch, factoring in critical elements like pitch speed, placement, and trajectory. Unlike simple plate discipline, DV measures the quality of a swing decision by rewarding hitters for engaging with pitches they can hit powerfully and for laying off those unlikely to yield positive results. Conversely, it penalizes decisions that miss hittable pitches or chase unpromising ones. This framework offers a profound insight into team-specific batting strategies, revealing how different organizations cultivate distinct approaches at the plate, which can vary significantly due to coaching philosophies, player recruitment, and even home stadium environments.
Swing decision strategies exhibit considerable diversity among MLB teams, driven by various factors. Historically, teams like the "Moneyball" Athletics prioritized patient hitters who specialized in drawing walks, capitalizing on the then-undervalued skill of plate discipline. Contemporary organizations, such as the Texas Rangers, actively standardize their player development processes to instill a consistent approach to swing decisions and overall plate presence. For instance, the Los Angeles Dodgers stand out with a superior DV of 108 in 2026, a testament to their deep roster of batters who consistently make excellent choices at the plate. Players like Kyle Tucker, Will Smith, Mookie Betts, Alex Freeland, and Freddie Freeman exemplify this prowess, demonstrating exceptional decision-making both within and outside the strike zone. The Dodgers maintain a low chase rate and high contact rate on pitches outside the zone, while also excelling at swinging at pitches labeled as "meatballs" within the zone.
In contrast, the Milwaukee Brewers, with a DV of 107, showcase a different strategic emphasis. While their overall DV is strong, they exhibit a significant divergence between their in-zone and out-of-zone decision metrics. The Brewers boast the best out-of-zone DV but struggle with in-zone pitches, indicating a predominantly passive approach that appears to be by design. This organizational philosophy is evident in players like Brandon Lockridge and Andrew Vaughn, whose swing rates have notably decreased after joining the team, reflecting a deliberate coaching directive to be more selective. This suggests a systemic shift in philosophy within the Brewers' coaching staff, aimed at reducing aggressive swings on pitches outside the zone, even if it means a lower zone swing rate.
The Chicago Cubs, with a DV of 106, mirror the Brewers' split in zone and out-of-zone decision metrics, albeit to a lesser extent. They also adopt a passive approach, swinging at fewer pitches than most teams, particularly within the strike zone. Key players like Alex Bregman, Michael Busch, and Dansby Swanson are central to the Cubs' swing decision performance, with Bregman maintaining an excellent approach despite a dip in power. Swanson's performance, while generally strong, has shown fluctuations, including a period of elevated chase rates and reduced swings at strikes, highlighting the dynamic nature of individual player tendencies within a team's overall strategy.
The New York Mets have experienced a notable decline in their team DV, dropping by eight points since 2025 to 100. This change is largely attributed to significant personnel turnover. While Juan Soto remains an elite hitter with an exceptional approach, the departure of key players like Brandon Nimmo, Jeff McNeil, and Pete Alonso, who were crucial to the Mets' strong DV in 2025, has impacted the team's overall performance. Their replacements, including Bo Bichette, Marcus Semien, and Carson Benge, bring varying levels of plate discipline. Bichette, in particular, has displayed a challenging approach with a high chase rate and a reduced zone swing rate, contributing to the team's increased chase rate this year compared to the previous season.
Finally, the Colorado Rockies present a unique case with the lowest DV at 89. Despite improving their DV from a staggering 63 in the previous year, they remain the most aggressive team at the plate. Their high zone DV is offset by the league's worst out-of-zone DV, driven by players like Ezequiel Tovar, Hunter Goodman, and Mickey Moniak, who exhibit exceptionally high chase rates. This aggressive approach is likely a deliberate organizational strategy, influenced by Coors Field's reputation as a hitter-friendly park where contact is heavily rewarded. The unique characteristics of Coors Field, which significantly enhance the outcome of batted balls, may lead teams to prioritize swinging more often, even at pitches outside the strike zone, to capitalize on the park's offensive advantages.
In conclusion, the analysis of team swing decisions through the Decision Value metric reveals a spectrum of strategic philosophies across Major League Baseball. From the Dodgers' consistent excellence in both zone and out-of-zone decisions, to the Brewers' and Cubs' deliberate passivity, and the Mets' adjustments due to roster changes, each team's approach is a complex interplay of coaching directives, player skills, and environmental factors like home ballpark characteristics. The Rockies' aggressive stance, in particular, underscores how specific park dynamics can influence a team's batting strategy, highlighting the multifaceted nature of offensive decision-making in professional baseball.
