August 29th, 2010
On this day in 2010, after initially ruling Brian McCann's drive a double, the umpires take just 86 seconds to overturn the call, making it the first time in baseball history a game ends with a walk-off home run thanks to a video review of a play. The backstop's ninth inning round-tripper, which clearly bounced off the top of the outfield wall and strikes a second barrier, gives the Braves a 7-6 comeback victory over Florida.
