Perfect game (baseball)

In baseball, a perfect game is a game in which one or more pitchers complete a minimum of nine innings with no batter from the opposing team reaching base safely. To achieve a perfect game, a team must not allow any opposing player to reach base by any means: no hits, walks, hit batsmen, catcher’s interference, fielder’s obstruction, and no fielding error, or uncaught third strike that allows a batter to reach base.
