Aquadome stadium - Hit a homerun into the pool at Steele Stadium, into the swamp at Gator Flats, and into the lake at Frasier Field. The Aquadome stadium should now be unlocked.
Better performance - Put Amir Khan and Achmed Khan on the same team and both of their skills will increase. The same happens when Ashley Webber and Sidney Webber are on the same team.
Easy second base - If the other team throws the ball to home play and you are on first base, you can run to second and they will not see you.
