A perfect game is defined by Major League Baseball as a game in which a pitcher (or combination of pitchers) pitches a victory that lasts a minimum of nine innings and in which no opposing player reaches base. Thus, the pitcher (or pitchers) cannot allow any hits, walks, hit batsmen, or any opposing player to reach base safely for any other reason: in short, "27 up, 27 down". The feat has been achieved 22 times in the history of major league baseball—20 times since the modern era began in 1900, most recently by Matt Cain of the San Francisco Giants on June 13, 2012
What's important to understand and appreciate here in Matt Cain's "Perfect Game" is that it's a TEAM EFFORT that gets the perfect result. This relates to any result where people work and play together...TEAMWORK WORKS.
