Plouffe is out of the lineup Wednesday against the Marlins, Susan Slusser of the San Francisco Chronicle reports.
The lack of a designated hitter spot will keep Plouffe glued to the bench Wednesday, but even if the game were being played in Oakland, the veteran third baseman wouldn't be guaranteed entry into the lineup. He ended up sitting out the Athletics' final two games against the Rays over the past weekend, so it seems Plouffe, who is hitting a career-worst .215/.278/.359 this season, may be playing himself out of an everyday role. Ryon Healy will man the hot corner Wednesday and could end up finding himself at the position on a regular basis.
