Higashio Osamu Kanshū: Pro Yakyū Stadium '91

Higashio Osamu Kanshū: Pro Yakyū Stadium '91 is a baseball simulation supervised by former professional baseball player Osamu Higashio. It features twelve Japanese national teams, each with abbreviated names of real players. The game can be played in Tournament Mode with one or two players for a series of matches against an opposing team, or in Pennant Mode in the Central or Pacific League, with the aim of becoming a champion, and the opportunity to play against Osamu Higashio's All-Star team.

Throughout the game, the player takes turns of playing three different roles:

• Batter = Simply move the batter and time the swings to hit the ball.
• Runner = Send the runner to one or more bases as fast as possible before the opposing team gets the ball.
• Pitcher = Control the throw strength and direction of the ball to get it past the batter.
