Rosario, 20, is batting .306 with one home run, two RBI and three steals through eight games for High-A St. Lucie.
The shortstop of the future for the Mets, Rosario should see Double-A shortly with a hot start. He did not hit a single home run in 103 games at High-A last season, though at just 19 years of age was among the youngest players at that level.
