What happened: MLB's automated ball-strike review system was used on a called second strike, and the challenge left the ruling unchanged. The decision adds another real-time test case for the league's ABS experiment during the 2026 regular season.

Why it matters: Each confirmed review adds evidence on how often the system changes a plate appearance versus backing the original call. That matters as MLB continues weighing the speed, accuracy and on-field value of an ABS challenge model.

What to watch: Watch whether upcoming ABS reviews begin producing more overturned calls as the season moves along. The frequency of changed rulings remains a key marker in how the challenge system is judged.
