This can work for any character. Immediately turn around and pick up the bat. Throw it at the Sandbag. You should not have to move much to pick it up again while it is still in the air. Throw it again. Repeat this process until you have about two seconds remaining. Then, go behind the bag and smash it. You should be able to get at least 1,500 feet every time. Note: Do not hesitate or wait until the bag is stopped. You will lose precious time. Also, you will have to turn around to face the bag after each hit.
