“He’s been huge for us, stepping up — he stepped up for us last year before breaking his foot,” fellow Mets’ starter Taijuan Walker said to MLB.com. “I think all of us, we just kind of just learn from each other and we kind of just kind of piggyback off each other. One guy has a good start, we just kind of keep the train rolling.”
The Mets’ lefty is relying heavily on his slider
Peterson was masterful on Sunday against the Miami Marlins, hurling seven innings while allowing just two earned runs. The Mets couldn’t win, but the southpaw kept them in the game, and the best part is that he didn’t walk anyone and struck out a season-high eight foes.
Paige Leckie of MLB.com detailed the key to Peterson’s excellent performance in 2022: the slider. 36 of his 50 strikeouts have come on the pitch. “I felt like I had a good feel of [my slider],” he said. “I could throw it where I wanted to put it, in spots I could get them to just swing over it. … I was able to keep them off-balance for the most part to be able to get those strikeouts.”
That has been the story the whole season: per FanGraphs, Peterson is using fewer fastballs (50.1 percent) and is going slider a career-high 27 percent of the time. If you have a good pitch, you should throw it often, and that’s what Peterson is doing.
As long as the Mets have Peterson healthy and in a groove, they will have an amazing wild card in the rotation, able to fill in for injured starters and, if everybody is healthy, pitch multiple innings from the bullpen.
