Yepez is not in the lineup for Tuesday's game against the Marlins, Bobby Blanco of MASNSports.com reports.
It's the second time on the bench in Washington's past three games for Yepez, who has gone 7-for-23 with two homers over his past seven contests. Andres Chaparro will shift to designated hitter while Joey Gallo starts at first base against Miami righty Max Meyer.
