The Mets are down an arm in the bullpen.
Manager Mickey Callaway announced before Saturday's game against the Royals that Robert Gsellman is headed to the IL with triceps tightness.
Callaway had said after Friday's game that Gsellman had not been available to pitch, and now the team will be without him for the immediate future.
To fill Gsellman's spot in the lineup, the Mets have called up right-hander Walker Lockett, who has made a handful of spot starts for the team this season.
Meanwhile, the news on JD Davis seems to be good.
After being pulled from the game on Friday in Kansas City, Davis said that he felt his calf act up a little bit, though it's something that he's dealt with multiple times in the past.
On Saturday, Callaway said that although Davis is not in the starting lineup, the outlook for him looks good.
"JD came in today feeling a lot better," Callaway said. "Just to make sure we're doing the right thing, he's not going to be in the lineup, but it sounds like he'll be available to pinch hit off the bench."
