MLB Miscellany: Rules, regulations and statistics. Perfect games and No-hitters: An official perfect game occurs when a pitcher (or pitchers) retires each batter on the opposing team during the entire course of a game, which consists of at least nine innings. In a perfect game, no batter reaches any base during the course of the game.
Let's also say  the average inning lasts 30 pitches (15 per half inning). We'll  approximate the total number of pitches per game at 270. That would  make 30 baseballs used per game (270 / 9). If all 30 teams played  the entire 162 scheduled games in a season, that would be 2,430  games played.
