Prospect Rundown: Amsterdam MohawksSummer Baseball
The Amsterdam Mohawks have been a formidable summer ball machine for years, but they have been particularly dominant in the 11 years since Keith Griffin took over as head coach. Griffin led the Mohawks to back-to-back championships in their final two seasons in the New York Collegiate Baseball League (2009-10), and this summer he guided Amsterdam to its fifth Perfect Game Collegiate Baseball League title in the nine-year history of the league. Amsterdam also finished as runner-up twice, and has not posted a winning percentage below .635 in any of Griffin’s 11 seasons at the helm.
Amsterdam can also boast an impressive pipeline to pro ball, with an alumni list that includes well over 100 players who went on to sign pro contracts. Fifty former Mowhawks were drafted between 2015 and 2018, and then 21 former Mohawks were drafted in 2019 (led by second-rounder Matt Gorski), along with two who signed as nondrafted free agents. Griffin said he just saw his 21st former player reach the major leagues, so he knows talent when he sees it.

After smacking 15 homers and posting a .944 OPS as a freshman this spring, Costes led the PGCBL with 12 home runs and a 1.272 OPS while ranking third in batting (.374). Not only did he dazzle with his power, but he showed impressive plate discipline, as he walked (22) more than he struck out (17), and nearly registered as many HBPs (15) as Ks. Super-physical at 6-foot-1, 215 pounds, Costes is an intimidating righthanded slugger whose approach has matured quickly.
“He was a high-end player at Maryland, and he can really do some things offensively. He really hits the breaking ball well too, advanced breaking ball hitter for a guy his age,” Griffin said. “That’s not to say …
