At the All-Star level, the ball moves in real time, giving you less reaction time in the field and at the plate. Rookie and Veteran levels move at less than real-time, giving you more time to react. You can change the difficulty level by choosing Game Settings from the Options menu. Check out the Controls section in the Player's Guide for a list of all Baseball 3D controller actions. In Baseball 3D, click User Settings on the Controls screen, then click Using Controllers.
Some commands require a combination of a button plus the directional controls.
Fielding If you're using a game pad, the four buttons are laid out like a baseball diamond. See the diagram.

Pitching The pitch energy boost lets your pitcher reach back and put a little extra mustard on his delivery. See the advanced tips below to learn how to use it.
