Haase is starting in left field and batting sixth in Sunday's game against the Rays.
Haase started at catcher Friday before getting a day off Saturday, and he'll now slide over to left field with Dustin Garneau picking up the start behind the plate. Haase has struggled this month with a .171/.239/.317 slash line, though he does have 21 home runs this season and could still provide some power for fantasy managers down the stretch.
