7. RHP Robert Gsellman
Scouting grades: Fastball: 55 | Curveball: 50 | Changeup: 55 | Control: 55 | Overall: 45After starting seven games for the Mets, Gsellman remains a main reason a postseason trip was even possible in 2016. His performance during that time resulted in a 2.42 ERA, 42 strikeouts in 44.2 innings and just one home run allowed.
This has catapulted the man who completes the long-hair trio of Mets starters into another possibly starting role in 2017, especially with the returns of Zack Wheeler, Matt Harvey, Jacob deGrom and Steven Matz all being from injuries.
So if Wheeler goes to the bullpen, or Terry Collins wants to use a six-man rotation at any point, Gsellman is their man to fill in.
