Left-hander David Peterson has won the final spot in the Mets’ rotation over righty Tylor Megill, as first reported Jon Heyman of the New York Post. Megill has been optioned to Triple-A, the team announced this afternoon. He’ll work out of the rotation there (as Abbey Mastracco of the New York Daily News reported earlier in the day).
The 27-year-old Peterson fired a dozen scoreless frames this season and remarkably allowed just one hit, although he also issued a troubling eight free passes. He overcame that shaky command both with the lack of hits and by punching out 13 of the 45 hitters he faced (28.9%). Megill, meanwhile, allowed 10 runs (seven earned) on 14 hits and 13 walks with a dozen strikeouts in 17 innings during Grapefruit League play.
A former first-round pick, Peterson has seen action in parts of three seasons with the Mets and generally fared well, logging a 4.26 ERA while fanning nearly a quarter of his opponents through 222 MLB frames. His career 10.7% walk rate is too high, but Peterson’s slider is a true bat-missing offering (47.9% whiff rate in 2022, per Statcast) and his changeup has been good enough to help keep right-handed opponents off balance. On many teams, he’d be locked into a rotation spot in the first place, but the deep-pocketed Mets spent extensively this offseason to fill out a rotation that saw Jacob deGrom, Chris Bassitt and Taijuan Walker depart as free agents.
Unfortunately, one of the arms signed to replace that outgoing trio was lefty Jose Quintana, who’ll miss upwards of half the season while recovering from a bone graft procedure to address a benign lesion on his ribcage. Peterson is a much better sixth starter option than many teams can afford, and given that he posted a 3.83 ERA in 105 2/3 frames last year, he could well parlay this opportunity into a more permanent rotation spot. Carlos Carrasco is a free agent at season’s end, and Max Scherzer has an opt-out in his contract.
Like Peterson, Megill is 27 years old and is a better depth option than many teams boast. The right-hander made 18 starts in 2021 and posted a 4.52 ERA with more impressive strikeout and walk rates (26.1% and 7.1%, respectively). He made six starts early in the 2022 season as well, logging a pristine 2.43 ERA with a huge 36-to-8 K/BB ratio in 33 1/3 innings of work while flashing an upper-90s heater that had added significant velocity since the 2021 season.
Unfortunately for both Megill and the Mets, a biceps injury shelved him into June, and he quickly returned to the injured list due to a shoulder strain. He wound up finishing the season with an ugly 5.13 ERA, though his early work is a reminder of the raw quality of his arsenal. Megill has stymied right-handed opponents to the tune of a .202/.247/.331 batting line in his career, but lefties have torched him for a .307/.368/.368 clip. He’ll continue working to find some answers against lefties while working out of the rotation in Syracuse. He’s likely the next man up if the Mets need another starter early in the season.
