The Minnesota Twins, alongside other MLB teams, are navigating a transformative period in baseball with the introduction of the Automated Ball-Strike (ABS) challenge system. This system has been tested in the minor leagues and now spring training games.
The ABS challenge system allows pitchers, batters, and catchers to challenge umpire calls in real time. It adds a new layer of strategy and excitement to the game. The ABS challenge system is set to make its debut in regular-season games as early as next year.
The Role of Pitch-Framing in Modern Baseball
Pitch-framing has become a critical skill for catchers in Major League Baseball, significantly impacting their overall value and compensation. Last season, the gap in pitch-framing ability between the best- and worst-graded catchers was substantial, equating to approximately two to three wins over a 162-game season.
This skill involves catchers subtly manipulating their glove movements to influence umpires’ calls, turning borderline pitches into strikes.
The Potential Impact of ABS on Pitch-Framing
With the introduction of the ABS challenge system, the value of pitch-framing could be greatly diminished or even eliminated if MLB fully adopts an automated strike zone in the future. While this scenario is still years away, the current challenge system already hints at a shift in how catchers will need to adapt their defensive strategies.
How the ABS Challenge System Works
The ABS challenge system allows pitchers, batters, and catchers to request a review of a specific pitch by the automated strike zone. Unlike managers, these players can challenge calls in real time, adding an element of energy and excitement to the game, similar to the challenge system in tennis.

The first inning of the Twins’ spring training opener showcased this system’s potential. Catcher Christian Vázquez successfully challenged a 2-2 slider. The call was overturned to a strike, ending a two-out jam.
The Strategic Importance of Judging Challenges
Catchers will now need to develop a keen sense of which borderline pitches are worth challenging. They also need to develop situational awareness to determine when to risk using one of their limited challenges.
This new responsibility could become as crucial as pitch-framing. Catchers who excel at making successful challenges will add significant value to their teams.
Early Results and Learning Curves
Triple-A teams, such as the St. Paul Saints, have been using the ABS challenge system for the past two years, providing valuable insights into its implementation.
The Saints’ success rate on ABS challenges improved from 36.8 percent in 2023 to 49.5 percent in 2024. This highlights the importance of situational awareness and experience.
Catchers Leading the Way
Data indicates that catchers are the most successful at initiating challenges, with a 57.1 percent success rate compared to 45.1 percent for hitters and 28.6 percent for pitchers.
This suggests that teams will likely rely heavily on veteran catchers to make challenge decisions. Veteran catchers have the ability to remain level-headed and discerning in high-pressure situations.
Future Implications for MLB
As the ABS challenge system becomes more integrated into regular-season games, it will inevitably influence how teams evaluate and utilize their catchers. The ability to successfully challenge calls could become a critical skill, potentially leading to a new era of strategic gameplay in baseball.
The Twins’ Approach
The Minnesota Twins are already preparing for this shift by encouraging their catchers to take the lead on challenges. They are also advising pitchers to only initiate challenges when they are confident in their correctness.
This approach aligns with the experiences of the St. Paul Saints, who found that catchers were the most effective at using the ABS challenge system.
Conclusion
The introduction of the ABS challenge system marks a significant evolution in baseball. It promises to alter the dynamics of how games are played and officiated. For catchers, this means adapting to new responsibilities and honing their judgment skills to add value to their teams. As we look ahead to the potential full implementation of an automated strike zone, the strategic use of challenges will become an essential aspect of the game. This will reshape the role of catchers in Major League Baseball.
