Great Baseball — About this game
Read the pitcher and build a rally in the Japanese Sega Card game. Six teams compete through batting, pitching and baserunning, with difficulty options that change how much fielding you control. A Home Run Contest gives you twenty pitches to turn into long hits. During a match, selecting the right runner matters as much as timing a swing: advance toward an open base, then retreat when the defense closes the route. This is the earlier card game, separate from the later export cartridge.
