Peterson had middling results in 15 starts for the Mets in 2021, but he was much better as a swingman last season with a 3.83 ERA across 105.1 innings. The lefty started in 19 of his 28 appearances and was effective in both roles. He added a tick to his fastball and more heavily mixed in his off-speed pitches, which helped lead to a 27.8 percent strikeout rate. New York is looking to bolster its rotation during the offseason -- whether it's by re-signing Jacob deGrom or bringing in a new face remains to be seen -- but Peterson pitched well last year and should have a chance to lock down a rotation spot during spring training. He has yet to show he can produce consistently year-to-year but is trending toward fantasy utility after a strong 2022. Read Past Outlooks
