David Peterson has already peaked
It’s easy to get fooled by the way David Peterson finished his 2023 season. The lefty had very pedestrian numbers on the year, going 3-8 with a 5.03 ERA in 111 innings of work mostly as a starter. Coming off of an impressive 2022 season which saw him pitch as a starter and reliever as well while bouncing more irregularly between the majors and minors, expectations were for Peterson to improve with a rotation spot locked in from the start due to injury. He failed to do so. His yo-yo career continued.
Now four seasons into his career, Peterson has posted seasons of a 3.44 ERA, 5.54, 3.83, and 5.03. It doesn’t guarantee next season falls below 4.00. In fact, we shouldn’t expect it to.
Peterson has been a model of inconsistency. He remains a bit too wild. The far bigger problem this past year were the hits. He gave up 10.1 per 9 innings of work.
We know Peterson can occasionally run into an awesome start. He has steadily increased his strikeout rate as well. The man can be a major league pitcher. It just might continue to come as a fifth starter or if the Mets feel so inclined, a move to the bullpen where maybe they unlock a different level.
