Attorney, Agent or FirmInternational ClassA63F 3/00 (20060101)AbstractAn electronic baseball game which includes a housing mounting a display centrally on an upper surface. On either side of the display are operator consoles for controlling a visiting team and a home team. At least one operator selects two lineups of players based on batting averages, throwing abilities, and the like. The operator controlling the team at bat selects when to hit by depressing keys which select different swings and controls runners in the attempt to reach and to steal bases. On defense, an operator controls the pitches thrown by the pitcher and the bases to which defensive fielders throw the ball in attempting to throw out the runners. An operator may also substitute in his batting order to obtain pinch hitters or relief pitchers. A special feature of the invention is that the results of each phase of the game depend on the characteristics of the players involved.Other References
