Extra Bases — About this game
Choose a baseball team, opposing club, field and starting pitcher before taking turns at bat and in the field. You control pitching, swinging, baserunning and throws rather than watching a purely managerial simulation. Relief pitchers and tactical choices let you respond as a match develops. Select a shorter five-inning game to learn the change between the batter view and the full diamond display.
