Los Angeles Dodgers manager Dave Roberts addressed the persistent struggles of releiver Will Klein, who has seen a drop-off in his pitching. Klein pitched four scoreless innings in the 18-inning Game 3 marathon against the Toronto Blue Jays last year, keeping the team in the game and throwing a career-high 72 pitches. His performance, especially considering how relatively unknown he was, earned respect and adoration from fans and the team, putting his name on the map. The righty had a sensational start to the season, with a 2.77 ERA in March and April and a 0.82 ERA in May.

In June, he had a 4.32 ERA in 8.1 innings and followed it up with a 7.71 ERA in 9.1 innings in July. Kleins latest rough outing came on Friday, when he came in during the second inning with a man on second and allowed the runner to score. Additionally, in the third inning, he gave up two hits and hit a batter, leading Roberts to pull him.All three runs for the Red Sox have come via Will Klein.Kleins ERA sits at 8.59 over the last 7 games and 5.06 over the last 15.Klein was great from March to May, June and July not so muchHe will be fighting for his spot once Blake Treinen is healthy. Nelson Espinal (@nelson__espinal) August 1, 2026Dave Roberts thoughts on Kleins strugglesWhile Roberts did not have a specific cause for Kleins woes, he pointed to the command that has really fallen apart. The team is seemingly digging into it, given how stark a contrast there is between both halves of his season thus far. Were still trying to dig into it, Roberts said. I thought there were some good fastball throws in there tonight, but the secondary stuff, thats kind of whats getting him. The sweeper is not a strike; is not getting chase from it. The curveball has a different shape to it than it did last year. So I dont know if its an arm thing, a mechanics thing, but thats something were trying to dig in on.Jul 31, 2026; Los Angeles, California, USA; Los Angeles Dodgers pitcher Will Klein (61) throws a pitch against the Boston Red Sox during the second inning at Dodger Stadium.
