This code works for any character and is helpful if you want trophies. First, when the contest starts, pick up the bat and throw it at the sandbag. This can be done by pressing the throw button and by holding down the control pad/joystick direction of the sandbag. This does about 20% damage, and then the bat should go near you. Pick it up again and repeat the process. In the end, the sandbag should have like 100% damage. Then use the home run swing to send sandbag flying about 1500 ft. I have achieved this with every character!
