White Sox pitcher Philip Humber threw the 21st perfect game in Major League Baseball history on Saturday afternoon, dominating the Seattle Mariners for nine innings without allowing a single baserunner.
Few clubs in baseball are as exclusive as the perfect game club; with just 21 (22, if you include Armando Galarraga's botched no hitter in 2010) members, it remains one of the premier pitching achievements of all time.

So grab your rosin bag and practice shaking off the catcher, and let's get started, shall we?
