Alvarez stayed in the game after his double in the seventh inning. He did not come out to catch in the eighth inning of the Mets’ 7-3 win over the Mariners in the MLB Little League Classic. Mets manager Carlos Mendoza said Alvarez would return to New York for an MRI. “Right now, we don’t know what we’re dealing with,” Mendoza said.

During the Mets' 7-3 win on Sunday against the Seattle Mariners during the Little League Classic in Williamsport, Álvarez suffered an apparent thumb injury when he slid headfirst into second base, legging out a hustle double during the bottom of the seventh inning.
