The Mets have claimed right-hander Antonio Santos off waivers from the Rockies, per a club announcement. Between this claim and the Mets’ earlier signing of outfielder Nick Plummer to a Major League contract, the team is up to 39 players on its 40-man roster.
Santos, 25, has spent parts of the past two seasons with the Rox but yielded 17 runs through 17 1/3 innings in his brief MLB auditions. He was also hit hard in 45 1/3 Triple-A frames in 2021, posting a 7.94 ERA with a 15.1% strikeout rate against a 12.7% walk rate. That said, Santos averages nearly 96 mph with his heater and complemented that primary offering with four secondary pitches.
Despite his impressive velocity, Santos hasn’t missed bats at a huge level in the minors (19.1% strikeout rate). However, he’s also walked only 5.1% of his opponents in the minors, and the resulting 14.1 K-BB% is at least somewhat intriguing when paired with that fastball and a deep arsenal of potential second/third pitches. Santos still has a minor league option remaining, too, so he can give the Mets some depth and flexibility in the bullpen this winter.
