Right in the middle of this network of caves underneath the grandstand is a batting cage. Mets players can practice their swing here in the middle of a game and not have to make their way back to the clubhouse or training room to do so. This one is located not far from the Mets dugout and has probably been used more by say Joe Orsulak, Danny Heep or Julio Franco than Darryl Strawberry or Mike Piazza... pinch hitters who need to take some extra batting practice during a game before being called in during the late innings by the Manager.
