Muncy is out of the lineup Monday against the Angels.
Muncy was the Athletics' regular starter at the keystone for much of August, but after accruing a .133/.246/.233 batting line over 69 plate appearances, it appears his run as an everyday player is over. He'll ride the pine for the fifth straight game Monday as manager Bob Melvin opts to lean on a platoon of Joe Wendle and Chad Pinder at second base.
