Treinen is sporting a 3.38 ERA with 10 strikeouts across eight innings pitched this season. He landed on the injured list in April with forearm tightness, and has spent the last few months recovering.

In 2024, Treinen was one of the Dodgers' best relievers as he posted an ERA of 1.93 with 56 strikeouts across 46.2 innings of work.

Wrobleski has a 4.50 ERA in the big leagues with 40 strikeouts in 40 innings of work this season. He has mainly served as a bulk arm out of the bullpen this year, but made his 2025 debut as a starter when the Dodgers' rotation was depleted.

Henriquez made his 2025 debut on July 22 against the Minnesota Twins. The right-hander made a grave error in the Dodgers' 10-7 loss when he fielded a slow grounder and threw it past first base into right field.

Henriquez's error was costly for the Dodgers as the bases were loaded and all runners scored.

This could go down as one of the worst games the Dodgers play all year.

Edgardo Henriquez (in his 2025 debut) fielded a slow grounder and proceeded to fire it past first base and into right field (all the way to the wall).

The bases were loaded. Everyone scored. Twins up 9-5.

Klein has made 10 appearances for the Dodgers this season, and is sporting a 3.38 ERA with 15 strikeouts across 10.2 innings of work.

The return of Treinen should provide a huge boost to a Dodgers bullpen that has struggled to maintain its elite form from 2024.
