The Nationals manager also said that the MRI on Espinosa's shoulder "revealed a little injury into his rotator cuff." Espinosa played through a torn left rotator cuff for more than a month at the end of last season, but he has said this year that it is not bothering him.
Espinosa also has a bone chip in his wrist stemming from a hit-by-pitch against the Braves on April 14. The 26-year-old repeatedly tried to play through the pain but is hitting just .158 (25-for-158) in 44 games this season.
Espinosa cleaned out his locker in the Nationals' clubhouse before Tuesday's game against the Mets.
