When fielding ground balls, Ali Aguilar learned an important lesson at the University of Washington: read the speed and direction of the ball to figure out what move to make. This means keeping your footwork efficient for the movement you are planning.
One drill to help this is the Pole Activation Drill:
Purpose: To keep your feet active on defense and to teach players to read the ball
How it works: Place infielders on the left of a PVC pipe or pole on the ground in the infield with a coach or player hitting ground balls from home plate. When the batter makes contact with the ball, the infield player hops to the right of the pole then makes a move to the ball back over the PVC pipe.
Variations: The coach or player hitting ground balls can mix up the balls that are hit so players have to account for speed, direction, and bounce.
