Robert Gsellman still is viewed as a potential starting pitcher within the Mets organization, but he will have to wait for his turn.
Until that opportunity arises, the 24-year-old righty will have to show he can succeed in a middle-relief role. Gsellman aced his initial test Thursday, when he struck out the side against the Cardinals in the seventh inning of the Mets’ season-opening victory.
“He can be very important, and I think that is why we pitched him in the situation we pitched him,” manager Mickey Callaway said. “This kid, you should see him come off the field, he was so pumped up and fired up it was like he just closed the game out.
