Rest-of-Season Projections
Signed a one-year contract with the Mariners in March of 2025. Traded to the Dodgers in June of 2025.
Recalled to Los Angeles
The Dodgers recalled Klein from Triple-A Oklahoma City on Friday.
Analysis
Klein owns a 3.38 ERA through 10.2 innings with the Dodgers this season but hasn't enjoyed the same success in Triple-A, where he carries a 6.23 ERA and 1.75 WHIP through 43.1 frames. Despite his performance in the minors, the Dodgers will bring him back onto the big-league roster to replace Michael Kopech (knee) in the bullpen. Klein will likely be limited to low-leverage situations.
