CLEVELAND -- The Twins would love for Trevor Larnach to become a consistent power threat from the middle of their lineup -- and he was exactly that for the first two months of 2022. But for the second season in a row, his performance looks to have been hampered by injury.

The Twins announced Monday that Larnach will undergo a bilateral surgical repair on Tuesday to treat the core muscle strain that sent him to the injured list on Saturday. The preliminary expectation is that Larnach could return to the field for the Twins in six weeks.

"That’s what we’re hopeful to get," president of baseball operations Derek Falvey said. "That’s what’s been reported to us, but again, probably have to do the surgery and get on the back end and make sure we feel good about how it went."

Larnach said he has been dealing with the pain near his pubic bone for around two to three weeks, and it steadily intensified until it was quite painful for him to get out of bed, lift weights and swing, at which point he and the Twins shut down activity and sought a second opinion in Philadelphia with a specialist for core muscle injuries.

Falvey said that Larnach was presented with several different options, including rest, an injection in the area and the surgical procedure, with Larnach ultimately making the decision to undergo surgery.

Though neither Larnach nor manager Rocco Baldelli fully linked the discomfort to the 25-year-old's sharp downtick in performance in June, the timelines seem to roughly line up.

At the end of May, Larnach was hitting .299/.375/.515 while playing nearly every day outside of a 13-game absence due to a right adductor strain. In June, he hit .127/.191/.238 in 19 games with only three extra-base hits in 68 plate appearances. Overall, he's hitting .231/.306/.406 this season with five homers and 13 doubles and has been worth 1.2 WAR, per Baseball-Reference.

Larnach was part of a similar situation last season, when he posted an .806 OPS through his first 50 career games before he skidded down to a .672 OPS and was sent down to Triple-A St. Paul in August. He later revealed that he had been playing through a hand injury that hampered his ability to swing.

"He's another guy that's really tough to take out of a lineup, for him to acknowledge any injury," Baldelli said. "He just does not do that very well. So for him to mention it, even in the first place, is kind of a big deal. We checked him out and realized there's something here, there's really something that we need to avoid putting him out there with."
