Angels Rotation Just Took Another Hit With George Klassen Sidelined

Despite George Klassen's promising stats, the Angels are forced to reshuffle their pitching rotation following his placement on the injured list.

The Angels lost George Klassen to the 15-day injured list on Sunday, a setback for a rotation that was already being stretched thin, but it also forces a change that could help a bullpen that has been asked to carry too much.

Klassen is dealing with lower back inflammation, and the move came before the Angels’ afternoon game against the Phillies in Anaheim. The right-hander said the discomfort showed up the morning after his start on Monday night, when he felt more sore than normal.

“Some movements feel a little restricted, but I mean, we're making progress right now,” Klassen said.

Even with only a month left in the season, Klassen said he is not worried this will become a long-term issue. He’s still playing catch, and he said his back already feels better than it did on Tuesday. The Angels, though, aren’t interested in forcing the issue.

“Just out of precaution,” Angels manager Kurt Suzuki said of putting Klassen on the injured list. “You want to make sure that we can get it before it turns into something big.

But he's not concerned about it. We're not concerned about it.

But just to stay ahead of it.”

Suzuki said the club has not yet discussed any innings management for Klassen, whose 118 innings between Triple-A Salt Lake and the majors are the most of his professional career.

Before the injury, the 24-year-old was on an upward run. Since returning to the big leagues at the beginning of August, he has posted a 2.01 ERA in four starts, striking out 18 over 22 1/3 innings.

“He's been making huge strides,” Suzuki said. “I think the consistency and those types of things have been getting better and better every time it gets out.

And you can kind of see the comfort level, I think, within every start. It gets a little bit more comfortable for every start and seeing the results.”

Klassen’s absence does create a short-term opening for the Angels, who had been using a six-man rotation since left-hander Yusei Kikuchi came off the injured list last week. That setup has taken a toll on the bullpen.

Since the Angels shifted to six starters, their relievers have put up a 5.18 ERA in 24 1/3 innings. That’s a sharp dip from the unit’s earlier run, when it ranked fifth-best in baseball since the All-Star break with a 3.12 ERA over 121 1/3 innings.

Because Klassen had been lined up to start on Monday, the rotation will move up a day. Right-hander Walbert Ureña will get the ball in the series opener against the Yankees on Monday.

Angels Rotation Hit With Another Setback At The Worst Time

The Angels took another hit to their pitching depth this week when rookie George Klassen landed on the 15-day injured list with left lower back inflammation, a setback that arrives as the club tries to patch together its rotation for the stretch run. The move was retroactive to Thursday, and it pushed Los Angeles back to a five-man rotation with Mitch Farris and Blake Weiman coming up to help absorb the innings.

Klassen is expected to be sidelined until at least September 11, leaving the Angels to manage without one of their young arms for the near term. Manager Kurt Suzuki said the issue is not season-ending, and Klassen is still hopeful the recovery will be minor, but for a team already dealing with rotation uncertainty, the timing could hardly be worse.

Angels Suddenly Face A Real Tyler Heineman Decision

Tyler Heinemans arrival gave the Angels a veteran catching option with a track record that suggested he could help stabilize the position, even if the bat was never going to be the main selling point. Acquired from the Blue Jays, he has continued to work through a difficult stretch at the plate since landing in Los Angeles, but the larger story around him has been less about numbers than about a player trying to show he still belongs in the majors.

Heineman has made it clear he wants to keep his MLB career going, leaning on his passion for the game and on the value he believes he can still provide when the moment gets tight. The challenge for the Angels is whether that belief lines up with the reality of his recent production, especially after a stronger 2025 season in Toronto and with the club now having to decide how much patience there is left for a catcher whose case rests more on trust and fit than offense.

Austin Gordon Is Giving The Angels A Rotation Question They Needed

Austin Gordon has spent the summer making a serious case that he belongs in the Angels long-term pitching conversation. The 23-year-old right-hander in the clubs minor league system was part of a combined no-hitter recently, and his work at Double-A has been even more eye-catching over a longer stretch, with a run of dominance that has turned heads inside the organization. For a team that is always searching for answers on the mound, that kind of rise matters.

Over his last eight starts, Gordon has gone 7-0 with a 1.88 ERA and has paired the results with a strong strikeout-to-walk profile, the sort of efficiency that usually gets player-development staff members paying closer attention. His performance has boosted his standing as a prospect, and it has put him on a path that could bring him into MLB consideration in the next year or two, even if the exact timing remains part of the story still unfolding.
