Notches eighth hold
PLos Angeles Angels
May 23, 2025
Zeferjahn recorded a hold against the Athletics on Thursday, allowing one hit and issuing one walk while striking out one batter in one scoreless inning.
ANALYSIS
Zeferjahn entered in the eighth inning with the Angels up two runs and quickly got into trouble, allowing a walk and a single to the first two batters he faced. However, the righty reliever then induced a double-play groundout before striking out Brent Rooker to escape the jam. Zeferjahn has claimed a high-leverage role in a beleaguered Angels bullpen -- he's registered a hold in five straight outings to move into the team lead with eight this season. His 4.50 ERA and 1.50 WHIP on the campaign aren't great, but he has 26 punchouts (along with 10 walks) in 18 frames while adding two wins and a save.
