The Minnesota Twins are demoting slumping infielder Royce Lewis to Triple-A St. Paul, The Athletic reported on Tuesday.

The report comes on the heels of the Twins sending outfielder Matt Wallner to St. Paul last week. Wallner had 22 homers last season.

The No. 1 overall pick of the 2017 MLB Draft, Lewis is batting .163 with three homers and 13 RBIs with 37 strikeouts in 31 games this season.

Lewis spent time on the 10-day injured list last month due to a left knee sprain. Before the injury, he was batting .222 with two home runs, two doubles and eight RBIs in 12 games this season.

Lewis, who turns 27 on June 5, is hitting .246 with 49 homers and 169 RBIs in 289 career games with the Twins.
