Old School Pitcher

David Peterson Brings Everyone Back to the Future Last Night

Gary Cohen called David Peterson an “old school pitcher that turned in an old school performance” after the game last night. There is no doubt the performance was old school, but rather than opining about whether Peterson is, let’s look at how sustainable this version of the Mets homegrown lefty can be.

Last year, advanced metrics were not kind to Peterson, who turned in a 10-3/2.90 performance. Not much has changed in 2025 as Peterson doesn’t fare well when viewed through the lens of expected batting average, exit velo, and strikeout rate. These numbers usually can indicate how sustainable and/or lucky a pitcher is. Pundits have come so far from the days of celebrating outcomes. Remember back in 2003 when Jae Seo gave up only one hit against the Miami Marlins, and Rick Peterson was criticized for dousing cold water on it because the Fish only swung and missed a couple of times?
