MINNEAPOLIS — Royce Lewis is indeed headed for a minor-league reset.With the idea that they can help their slumping slugger turn things around, the Minnesota Twins demoted Lewis to Triple-A St. Paul on Tuesday morning. The move comes five days after the Twins made a similar decision with Matt Wallner.Responsible for some of the team’s biggest playoff successes of the past 25 years, Lewis was striking out a career-high 31.1 percent of the time and batting only .163/.261/.279 with three home runs and 13 RBIs through 119 plate appearances.To replace Lewis, whom the team selected with the first pick of the 2017 draft, the Twins purchased the contract of veteran infielder Orlando Arcia, who is hitting .318/.376/.556 with eight home runs for St. Paul. The team designated reliever Justin Topa for assignment to make space for Arcia on the 40-man roster.“(This is) obviously not something that we were hoping to have to do,” Twins general manager Jeremy Zoll said. “But we also know there’s a really good player in there that’s had a ton of great moments for this organization, and I think there still are more to come here.”Along with Lewis, the Twins announced catcher Ryan Jeffers is being placed on the 10-day injured list with a left hamate bone fracture. Jeffers exited Monday’s game several minutes after fouling off a pitch.The team also purchased the contract of catcher Alex Jackson from St. Paul and recalled pitcher Travis Adams. To make space on the 40-man roster for Jackson, the Twins transferred pitcher Garrett Acton from the 10-day IL to the 60-day IL.Though the decision to demote a player with Lewis’ status carries significance, it’s hardly shocking. Lewis’ struggles have been pronounced since returning from an IL stint on April 21, with 25 strikeouts in 74 plate appearances and a .380 OPS.Twins manager Derek Shelton said Lewis needs to regain consistency with his swings.“Is it a mental thing?” Shelton said. “Yeah, probably in some respect when you’re struggling at the major-league level. This is not just for Royce’s case, but any player that is struggling at the major-league level. Mentally, you need to go down there and have some success because of the fact if you’re not doing that, it will weigh on you. I do think there is some adjustments with his swing and what he’s doing day-to-day that we just need to see more consistency with.”After working to adjust his swing in the offseason, Lewis got off to a decent start, producing an .822 OPS through his first dozen games. Lewis was walking more than ever and hitting for some power, but he has been out of sorts since spraining his knee in early April.Lewis’ slump grew increasingly worse over the past two weeks.During a two-day break from the lineup to work on his swing, Lewis indicated he was worried about job security, believing the front office wanted him to fail to write him off. Since returning, Lewis struck out 10 times in 30 plate appearances. He also made an uncharacteristic and costly error in Saturday’s one-run loss, whiffing on a potential inning-ending double-play ball that led to a run scoring.“The reality is as we work through it and try to think through what’s best for Royce and for the organization, giving him that reset in Triple A to hopefully get him going and get that confidence back is what’s best,” Zoll said. “(There’s) a lot of season left.”Originally in a battle for the final roster spot at the end of spring, Arcia has been outstanding all season at St. Paul. The Twins elected to promote Arcia over prospect Kaelen Culpepper.One reason the Twins opted for Arcia is his experience and versatility; the other is that they want Culpepper to further develop before bringing him to the big leagues.Selected with the 21st pick of the 2024 MLB Draft, Culpepper is heating up with a .985 OPS and four homers in 67 plate appearances in May. Team officials like what they’ve seen from Culpepper but want to give him more time to work on his defense at shortstop and improve his offensive consistency at the plate.In selecting Arcia over Culpepper, the Twins essentially left the door open for Lewis to make a triumphant return. All Lewis needs now is to get himself right. The Twins think facing Triple-A pitching could be the key.“We want to see the player, the confidence, the performance that we know he’s capable of,” Zoll said. “If he’s performing down there and the underlying metrics support the performance, then we’ll be ready to bring him back and have him help us. … Sometimes it’s as simple as just having some good results to build up confidence, take some pressure off yourself, allow those mechanical adjustments to set in.”
