Chicago White Sox at Seattle Mariners

The Chicago White Sox secured a 5-1 victory over the Seattle Mariners in their spring matchup at Peoria Stadium, with the ABS story centered on the Mariners’ challenge success rate, which stood at an impressive 75%, overturning three of their four calls. Each overturned pitch call related directly to strike calls that were changed in the Mariners’ favor, adjusting counts during key moments of their plate appearances. Despite this, Seattle’s inability to convert those opportunities into runs underscored a striking gap between challenge success and overall offensive output.

Seattle's challenges mainly revolved around called strikes that, when overturned, reset counts and potentially extended at-bats. Two notable instances occurred in the bottom of the seventh inning with Brian O’Keefe, where two strike calls were overturned, changing the count from 2-0 to 1-1 and then from 1-0 to 0-1 as the Mariners were trailing 3-0. Earlier, in the bottom of the second inning, an overturned called strike against Mitch Garver at a 1-0 count likewise adjusted the count to 0-1 in a scoreless tie, showing Mariners’ persistence in contesting borderline strikes.
