From MobyGames:

   Great Baseball is a sports game developed and published by Sega for the Sega Master System as part of the 'Great' series of sports games. This Great Baseball should not be confused with the Great Baseball released in Japan and Taiwan. An upgraded version of this Great Baseball would later that year be released in Japan as The Pro Yakyuu: Pennant Race.
   Every play in the major league is brought to this diamond. So pitch, swing, and steal bases like the pros. Play ball!! Play Great Baseball with another player or against the CPU. Next, choose to play with or against different teams including New York, Toronto, Milwaukee, Chicago, Seattle, Boston, and many others. Finally, select your pitcher and his specialty and stamina, and away you go.
