R.B.I. Baseball provides baseball fans with ten regular teams and the two all-star teams to choose from, each using a blend of real 1986 and 1987 rosters and stats for the cities (or leagues) they represent. Hit a home run with a rookie known as Mark McGwire. Or strike him out as Houston with a guy who threw a few K's in his time, Nolan Ryan. ~ Christopher Michael Baker, All Game Guide
