Montero will play first base and bat cleanup Saturday against Pittsburgh, Patrick Lyons of JustBaseball.com reports.
Brenton Doyle (knee) was scratched from the lineup Saturday, and as a result Jake Cave will move to center field as Michael Toglia moves to right, opening up first base for Montero. Montero has just two hits in his last 23 at-bats and owns a .546 OPS on the year.
