Glitch: Thrown out on a walk:
Walk the batter, then have the pitcher throw the ball to first base as he is walking to the base. The batter will be called out if the ball reaches first base before he does. Note: This may freeze the game.

Glitch: Thrown out after a single:
After the CPU gets a single, throw the ball to the catcher then go to first base and throw it to the first baseman. The runner will be out.
