Escobar was replaced in Monday's game against the Reds in the fifth inning due to an undisclosed issue, James Wagner of the Washington Post reports. It's not clear what prompted Escobar's early departure from the game, but he's the second Nationals player to hit the bench after Denard Span was lifted in the second inning with a suspected injury. Dan Uggla came on to replace Escobar, whose condition should be updated after the game.
