Watch as Coach Josh Bloomer explains, and infielders demonstrate this palm up vs. palm down groundball drill. The ball always dictates where an infielder's glove should be. If a groundball is coming to a fielder and it is on its way up, then the fielder's palm should be forward. If the ball is on its way down, the palm should be up so the fielder can scoop it.
Josh Bloomer was previously a coach at Duke University and the University of Arizona.
