David Peterson

Peterson was needed for 27 appearances (21 starts) for the Mets last season as the team battled numerous injury issues in their rotation. On the positive side, Peterson struck out 128 batters across his 111 innings, marking the second year in a row he's fanned well over a batter per frame. On the negative side, Peterson also had a walk rate over 10 percent for the second straight year and wound up finishing with an ERA over 5.00. The left-hander underwent left hip surgery in early November and a rough timetable has him returning around June. Pitchers that can miss bats and get groundballs like Peterson are usually ones you want to bet on. The southpaw has yet to throw strikes consistently in the big leagues, though, and isn't necessarily guaranteed a rotation spot once healthy. Read Past Outlooks
