Trout, a three-time AL MVP and 11-time All-Star, suffered a torn meniscus in his left knee in Monday’s 6-5 win over the Phillies and will undergo surgery in the coming days, general manager Perry Minasian announced. It’s not expected to be a season-ending operation, but no immediate timetable was provided from the Angels or Trout.

“It’s tough,” said an emotional Trout prior to the Angels’ 7-5 loss to the Phillies on Tuesday night at Angel Stadium. “It’s just frustrating. But we’ll get through it.”

Trout, 32, said the hardest part is he’s not even sure when he sustained the injury. He had no knee issues leading up to Monday’s series opener, but felt something while jogging off the field in the third inning. Trout continued to play through the injury, including stealing second base in the seventh inning and scoring the eventual winning run from second base on a wild pitch. But his knee continued to worsen and he underwent an MRI exam on Tuesday that revealed the damage.

“It’s crazy because when I look back, I don’t even know when I did it,” Trout said. “In the third inning when I was going back to the dugout, I felt an ache, but just like a little ache where it was more like, ‘This is weird.’ Didn’t think anything of it and was hitting and running and didn’t feel anything. Stole second, felt nothing. It was just after I did activity and sat back down and got back up, that’s when I felt it.”

Trout was off to a strong start to his season with a .220/.325/.541 line and 10 home runs, which were tied with Gunnar Henderson for the most in the Majors. Trout has also been more active on the bases this year, with as many steals (six) as he had in the last four years combined.

Trout called it another freak injury that was out of his control and was clearly frustrated by the prospect of missing time yet again.

“It’s all guesses, trying to pinpoint where this came from,” Trout said. “You play the game hard and [stuff] happens.”

Unfortunately for Trout and the Angels, injuries have become a recurring theme in recent years. Trout played in just 82 games last year due to a fractured wrist and 36 games in 2021 due to a right calf strain. He cleared 100 games played in 2022 but has not played in 130 or more games since 2019.

“We’re going to miss Mike,” manager Ron Washington said. “I think we know what he means to this organization. But the thing about baseball is, when there’s a game on the schedule, you have to play. Some guys are going to get the opportunity that they’ve been craving. Now, we’re going to see what they’re going to do.”
