The successful execution of a baseball strategy in time is very important in the baseball game. The key point for this successful execution capability of a player does not only depend just on the daily routine practice, but also depend heavily on the correct concepts a player has. In this paper, we design and implement two animation assisted sport simulation subsystems, the Cutoff Play Training Subsystem and the Editable Fielding Strategy Training Subsystem, for general baseball fielding training. These two integrated training subsystems allow users to choose what happens once the baseball is put into play, and provides many different scenarios and cases that probably will occur in the baseball field. By using these animation simulation subsystems, players, especially those at the amateur junior level, can improve greatly on all aspects of fielding plays in a short period of time.
