Big thanks to @TheCanesBB alum and current @Mets LHP @ColtonCosper for joining @FEveritte16 on tonight’s Recruiting zoom sharing knowledge to some 2028s!

Two non top 30 Mets prospects to keep eye on in 2026 milb season are LHP and "kitchen sink" thrower Colton Cosper along with New York born IF/OF Nick Roselli. Curious what lab can do with Cosper velo and Roselli offseason training has reportedly been fantastic.

UPDATE

The Mets have claimed right-hander Cooper Criswell off waivers, per @jorgecastillo

In 2025, Criswell appeared in seven games for the Red Sox, holding a 3.57 ERA in 17.2 IP.
