The Twins placed Prielipp on the 15-day injured list Thursday with a blister on his left middle finger.
Prielipp started Wednesday's game against the Guardians but didn't factor into the decision after allowing three runs on four hits and two walks with six strikeouts across five innings. The rookie has a 5.00 ERA, 1.37 WHIP and 71:25 K:BB across 66.2 innings. He'll be sidelined through the All-Star break.
