Escobar is available in an emergency situation Sunday. The Nationals have a day off on Monday, and the team is hoping that Escobar will be back in the starting lineup against the Cardinals on Tuesday.
Escobar injured the groin in the fourth inning Friday while running to first on a groundout to Phillies shortstop Freddy Galvis. Escobar exited before the top of the fifth and was replaced by Dan Uggla, who entered the game at second base while Danny Espinosa went from second to third base.
