Philadelphia Phillies catcher J.T. Realmuto may not love the new Automated Ball-Strike (ABS) challenge system, but he showed just how valuable it can be during a recent spring training game.

In a rare moment that perfectly illustrated the system’s impact, Realmuto successfully challenged two pitches in the same inning, turning both calls into strikeouts for his pitcher.
How the Sequence Happened

During the inning, the home-plate umpire initially ruled two separate pitches as balls. Realmuto immediately felt both calls were incorrect and used the ABS challenge system to review them.
Both challenges were successful.
After the automated strike zone review, the pitches were overturned and ruled strikes, instantly changing the count on each batter and resulting in two strikeouts.
Instead of extended at-bats, the Phillies pitcher walked away with two outs thanks to Realmuto’s awareness behind the plate.
A Perfect Example of the ABS System

Major League Baseball introduced the ABS challenge system this season to allow players to contest questionable ball-and-strike calls.
Each team receives two challenges per game. If the challenge is successful, the team keeps it.
The system relies on automated strike-zone tracking to determine whether the pitch crossed the zone.
Realmuto’s quick decisions showed exactly how catchers can influence games with the new rule.
Realmuto Has Mixed Feelings About ABS

Despite the successful challenges, Realmuto has previously said the system adds extra responsibility for catchers.
Between game-planning with pitchers, studying hitters, and managing the defense, catchers already carry a heavy workload.

Now they must also decide when a pitch is worth challenging — taking into account:
- The count
- The game situation
- Whether the pitch actually clipped the strike zone
Even with those concerns, Realmuto’s performance showed how the system can reward experienced players who know the strike zone well.
Veteran Awareness Behind the Plate

Realmuto has long been considered one of the most complete catchers in baseball, known for his leadership, defense, and game management.
Moments like this reinforce why pitchers trust him so much.
Two quick ABS challenges may not seem like a big moment in a spring game, but it demonstrated something important: a veteran catcher can still control the game in new ways, even as baseball continues to evolve. ⚾
