New York Yankees manager Aaron Boone, who was previously known for frequently arguing with umpires and leading the league in ejections for five consecutive seasons, has not been ejected from a single game so far in 2026. Boone credits this change in behavior to the new automated balls and strikes (ABS) challenge system, which allows teams to appeal incorrect ball and strike calls to a computerized tracking system.

Why it matters

Boone's ability to keep his cool and avoid confrontations with umpires represents a significant shift in his managerial style, which was previously marked by a combative approach. The ABS system has provided Boone with a new tool to address questionable calls, reducing his need to argue directly with umpires and potentially get ejected from games.

The details

Through the first part of the 2026 season, the Yankees have won 57% of their ABS challenges, ranking 12th in MLB. Some teams have had even greater success, with the Reds winning 70% of their challenges. Boone acknowledged that the ABS system has changed his approach, stating, 'I thought (the ABS challenge system) was going to make me another layer of something to be upset about, but I'm changing my tune on that a little bit.' The manager also noted that he doesn't want to get ejected from games, contrary to his previous reputation.

• Through Tuesday, the Yankees had won 57 percent of their ABS challenges, per Codify Baseball, which ranks 12th in MLB.

What’s next
