As if the Mets needed any more questions about their bullpen, they may have another injury to deal with after Friday's game.
Robert Gsellman pitched a scoreless seventh inning for the Mets, but was then taken out of the game as part of a double switch. When asked about that move after the game, Mickey Callaway said Gsellman told him he was experiencing tightness in his back.
Callaway didn't have much more info on Gsellman, other than that he will get treatment and the team would go from there.
The 23-year-old is 1-1 on the season for the Mets with a 4.91 ERA.
The Mets also designated Hector Santiago after the game, who allowed another run on Friday, and will keep Tyler Bashlor, Friday's 26th man, on the roster.
