The Pirates beat the Giants 2-1 on Tuesday evening on what was the first game winning video review.
In the bottom of the ninth with two outs, Pirates left-fielder Starling Marte smacked a pitch to the right field wall.
Hunter Pence fielded the ball as Marte ran to third base, then a wild throw from second baseman Ehire Adrianza allowed Marte a chance to score at home plate.
Marte slid into home and the umpire’s initial call was that Marte was out. But upon further review, Marte had gotten his right hand on the base before Buster Posey tagged him on the chest. With that score, not only did the Pirates win the game but it was the first walk off replay challenge for Major League Baseball.
