The Pro Yakyuu '91 — About this game
The Pro Yakyuu '91 brings twelve Japanese professional teams and named players to Game Gear. Play a baseball game or concentrate on hitting in the home-run contest. In a match, the rhythm changes between waiting for a good pitch, choosing how to deliver the next ball and reacting when it enters the field. Before a throw, check the runners and decide which base matters most; a hurried choice can give up an extra advance. At bat, avoid swinging automatically at every delivery. Use a first game against the computer to learn the change of roles, then pay closer attention to advancing and returning runners once the basic timing feels familiar.
