Mauricio, the switch-hitting wunderkind who was once the top prospect in the Mets' system but tore his ACL playing winter ball in December 2023, is being called up from Triple-A Syracuse after just 65 minor league at-bats this year, a source confirmed.

Mauricio, a switch-hitter, started at third base and batted seventh. The Mets won’t know the severity of Vientos’ injury until they get his MRI results. On Tuesday night, Vientos flew to New York, where he was scheduled to do the test.

Ronny Mauricio has made it back to the majors. The former top prospect is being promoted Tuesday and will join the team in Los Angeles for the second matchup of its four-game set with the Dodgers, The Post’s Joel Sherman confirmed.
