Alvarez (hand) took live batting practice on the field Tuesday, Anthony DiComo of MLB.com reports.
Alvarez had been hitting in the cage, but Tuesday marked the first time that he took batting practice on the field since he underwent surgery on a fractured hamate bone in his left hand back on March 10. While the Mets haven't revealed a specific timetable for their starting catcher's return, Alvarez's recovery has come along nicely, and he could make it back before the end of April if all goes well.
