Mountcastle (hand) isn't starting Wednesday's game against the Twins, Roch Kubatko of MASNSports.com reports.
Mountcastle exited Tuesday's game against the Twins after he was hit on the hand by a pitch. He was diagnosed with a bruised left hand after X-rays came back negative, and he's still considered day-to-day. Mountcastle likely won't be available off the bench Wednesday, Dan Connolly of The Athletic reports. Anthony Santander will serve as the designated hitter while DJ Stewart shifts to right field.
