Win a single player exhibition game with any player to unlock his or her M.V.P. profile at the "Exhibition Records" screen.
Go to Exhibition mode and play with two players. Have player two as the pitching team, and player one as the batting team. Press A to pitch the ball. As soon as you press A, when player 2 is preparing to pitch, quickly go to player one and charge up for a charge swing. Then, hit the ball when your character is fully charged. Most of the time you will get a homerun. Note: Using characters such as Wario, Donkey Kong, Bowser, and other power type characters is recommended.
You can complete Challenge mode quickly if you use Peach's or Yoshi's team.
While pitching with Mario, press A to make him start his wind-up. When he reaches the top of his jump, press A again to make his pitch a "nice". Note: This may require a few attempts.
