This drill is a well known drill to get more bat power and work on any part of the swing that a player may need to work on.
Set up in a soft toss situation. The tosser should set themselves at the batting side of the batter and ahead of the batter as well.
Each toss should be approximately tossed at the hip of the batter. The toss should be crisp, but not too fast and out in front of the batter. Practice the toss to get it correct.
Now, toss the balls to the batter’s desire and focus on proper hitting mechanics
