Trevor Plouffe moved from left field to second base to take Casilla's place in the lineup, while Chris Parmelee made his first career start in left field.
Parmelee saw one inning of action in right field on Wednesday, but that was his only outfield experience in the Majors prior to Monday. In the Minors, Parmelee made 286 starts in the outfield, but only four of those came in left field.
"Parmelee's been running around out there, taking all kinds of work out there in left field," manager Ron Gardenhire said. "He's excited about it."
