Berkman, a 37-year-old with a history of knee trouble, suffered an injury to his hip or lower back running to first base in Saturday’s 9-5 loss to Houston. He stayed in the game for one more at-bat before leaving in the seventh inning.
Tepesch went to the DL with right elbow inflammation two days after getting the win in a 10-5 victory against the Astros. The 24-year-old was playing catch Saturday when he said his elbow was sore, and Washington said the move was precautionary.
