Rest-of-Season Projections
Notches eighth hold
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.

Latest Fantasy Rumors
Could end up being traded
Zeferjahn is one of several Angels players who might be on the move closer to the trade deadline, according to Jim Bowden of The Athletic.
ANALYSIS
The Angels have several relievers that could generate some trade interest as the deadline approaches, and it's not out of the question to see Zeferjahn moving to a different team in the coming weeks. The 27-year-old right-hander hasn't given up runs in eight of his last nine outings while posting a 3.12 ERA and a 1.38 WHIP over 8.2 innings in that stretch. For the season, he owns a 4.56 ERA on 23.2 innings, but he posted an impressive 2.12 ERA, albeit on a limited sample size, across 12 appearances in 2024.
