One and Cover

This is a somewhat more advanced drill. Place players in infield positions including catcher. Hit  a ground ball to one of the infielders and have the fielder make the throw to first. The player that fielded the ground ball should then cover his/her base and the catcher will make a throw to that base as if a runner is stealing. Outfielders should be backing up each throw.

You can mix it up a bit by having the shortstop take throws at third base after balls hit to the third baseman or have the second baseman cover second after balls hit to short, etc.

You can also have the infielders throw around the horn to end each sequence.
