I do a different variation of the Barry Bonds drill. Same basic idea, though. Player lines up at the plate and hits the ball. After she hits it she takes a step forward. Easy way to do it is to do a crossover step. Every time she hits the ball she moves up a step (rather than getting three to five pitches) to keep her from getting too groove in to particular timing.
After she can no longer catch up to the ball, I send her back to the original plate. The objective is to learn to hit slow pitches, which a lot of people don't spend time doing. They focus on the fast stuff, then wind up going apoplectic when their teams can't hit some kid throwing 45 mph meatballs and lose. After all the fast stuff, the ball at the original plate looks awfully slow. I try to prepare for all eventualities.
