pthawaii, a drill we did a lot when working with infielders was to set up a bucket or chair or... and go out half way to the player's position. Then, we threw groundballs and instructed. By throwing then, you can get a good angle on the ball and get a lot of repetitions on any particular ball. We did this for standard positions, for balls in the hole and for run through balls. Naturally, we moved back and hit fungos later on similar balls.
pthawaii, have you done the footwork drills necessary for fielding a ball? Most of the footwork drills we did involved placing a ball on the ground in two or three positions and the players worked on footwork approaching the ball. I had players keep a ball in their glove so that they didn't have to replace the ball on the ground. So, the do thier "creep or crawl in" simulating their footwork on the pitch and then do the appropriate footwork to receive the ball and throw. They don't necessairly have to complete the throw.
Finally, we talk to our players with certain cues. We "land a plane" and not a "helicopter." We "go quick to go slow." I believe in "bulldozer through the ball." (Fielding through the ball.)
I don't know if any of this helps. Good luck.
