The Mets placed Baxter on the 15-day disabled list on Sunday with a displaced right collarbone and fractured rib cartilage next to the sternum. They recalled infielder Josh Satin from Triple-A Buffalo to take Baxter's place on the roster.
Baxter slammed into the left-field wall at Citi Field to make the catch on Yadier Molina's drive in the seventh inning on Friday night, preserving Santana's eventual no-hitter, the first in franchise history. Baxter was diagnosed with his injury on Saturday and likely will miss six weeks.
Baxter has hit .323 with a .915 OPS in 40 games for the Mets this season.
Satin, 27 was hitting .274 with three home runs and 15 RBIs for Buffalo. He has appeared mostly at first base but has also spent some time at second and third.
Satin made his Major League debut for the Mets last season, hitting .200 with two RBIs in 15 games.
