Gsellman allowed four runs on seven hits and two walks over five innings Friday while striking out six. He did not factor into the decision.
Gsellman isn't making anyone forget about Matt Harvey, but he's providing the Mets with solid, gutsy innings at a critical point in their season, meaning that he could be a source of value in deeper formats. He has 17 strikeouts, a 3.92 ERA and a 1.50 WHIP in 20.2 innings since being called up in August. His next test will be against Washington and Tanner Roark on September 14.
