Posey will sit Monday against Arizona, Alex Pavlovic of NBC Sports Bay Area reports.

EDGE Analysis

The Giants have managed Posey's playing time carefully this season, only once asking him to start more than two games in a row. He'll head back to the bench after making just one start this time around, though he's started three days in a row, getting the call in the afternoon portion of Saturday's doubleheader against the Nationals. Curt Casali starts behind the plate in his absence.
