Enter the "My MVP" screen, then create a player with the name "Dan Carter" to unlock all MVP rewards. If you entered the code correctly, a message will appear.
Enter season mode, then start the next game that you are ready to play. When trying to get easy steals for MVP points, have two or more players on base with no outs. Before hitting the ball, send the signal for the players to steal. Select the third base runner to steal home, the first base runner to steal second, and the second base runner to setal third. Doing this will result in two stolen bases, or if you are lucky, even three.
