MINNEAPOLIS -- The Minnesota Twins have lost eight of 10 series in May, with a lineup that's been limping along lately with a spate of injuries and too many strikeouts.

They could use a boost. Royce Lewis is on his way.

Lewis will join the Twins in Houston, where they'll start a three-game series Monday. The first overall pick in the 2017 draft will be reinstated from the 60-day injured list and return to action exactly one year from the date of the torn ACL in his right knee that limited his major league debut to 12 games.

Manager Rocco Baldelli announced the move after a 3-0 loss to Toronto on Sunday. Outfielders Kyle Garlick and Matt Wallner will be sent down to Triple-A St. Paul, where Lewis has been playing on a rehab assignment. Outfielder Max Kepler will also be reinstated from the 10-day injured list, after missing 14 games with a strained left hamstring.

"This is a culmination of a lot of hard work from Royce. I'm excited to see Royce back out on the field. He can jolt you with the enthusiasm and all of the exciting things that he can do, but he's a good young player and he's had a long road to get back to this point," Baldelli said.

Lewis batted .333 with four homers and 10 RBIs with a 1.098 OPS in eight games on his rehab assignment with the Saints. Manager Toby Gardenhire delivered the news, Baldelli said.

"All the reports have him in a good place, and he's done a good job following through on everything he's needed to do," Baldelli said. "Now, he's ready."

Lewis batted .300 with four doubles, two home runs -- including a grand slam - and five RBIs in 12 games for the Twins last season. He was drafted as a shortstop, but since the arrival of Carlos Correa last year he has made the transition to third base and will likely be a fixture there for the foreseeable future.

Second baseman Jorge Polanco (strained left hamstring) and outfielder Trevor Larnach (pneumonia) are two other regulars who remain out. Polanco went through a pregame workout and is eligible to return anytime, but Baldelli said he'll continue to be evaluated daily before a decision is made. Kyle Farmer and Edouard Julien can play second base in the meantime.

Wallner was sent back to Triple-A in a roster-management game despite reaching base eight straight times.
