baseballI just found this paper by Yuko Uematsu and Hideo Saito of the Graduate School of Science and Technology in Japan.  Titled “Visual Enhancement for Sports Entertainment by Vision-Based Augmented Reality”, it discusses ways that Augmented Reality can aid in simple sports games.  Two specific examples include replays of classic Baseball games, and an interactive bowling game.

AR Baseball Presentation System is an observation system of a virtual baseball game. Users place a real baseball field model on the tabletop and input a baseball game history (scorebook) that they want to watch into the system. Then, they can watch the game by replaying with virtual baseball players on the field model in front of them. On the field model, 2D markers are placed for registration of the virtual players. Therefore, the users can watch the game from their favorite viewpoints around the field.

The entire paper is available at Hindawi publishing as a PDF.
