Mauricio was recalled from Triple-A Syracuse on Friday.
Mauricio is playing second base and batting ninth for the Mets on Friday versus the Mariners in his major-league debut. The 22-year-old has batted .292/.346/.506 with 23 home runs and 24 stolen bases this season with Syracuse. A switch hitter, Mauricio is expected to see most of his playing time at second base but is capable of handling shortstop, third base and left field as well.
