David Peterson

Peterson didn't make his 2024 debut until late May after recovering from offseason hip surgery. He wound up being a key piece in the rotation for a Mets team that made it to the NLCS, and the left-hander was particularly good down the stretch with a 2.41 ERA, 1.14 WHIP and 58:20 K:BB over 67.1 frames during the final two months of the regular season. Like many pitchers on the Mets staff last season, Peterson embraced the sinker, using it as his fastball of choice for the first time in his career. While he sported a 50.1 percent ground ball rate, Peterson also watched his strikeout rate plummet from 26 percent to 19.8 percent. His velocity was fine, and Peterson can still be quite effective with a high ground ball rate if he can just get the strikeout rate back to even a league-average level. That said, with such a large gap between his xERA (4.59) and actual ERA (2.90), some level of regression from the southpaw looks to be a safe bet. Read Past Outlooks
