Pro Yakyuu Super League CD is a baseball game developed and published by Sega for the Mega-CD. It is the first of two Super League games to be released on the CD peripheral, and only in Japan. The second would be Egawa Suguro no Super League CD the following year.
Like other games in the series, it uses the Nippon Professional Baseball license and features all the Central and Pacific League teams and rosters, and depicts the action from behind the batter which cuts to an overhead view when fielding and running the bases. It has few CD-enhanced touches besides redbook audio BGM that plays throughout the game.
