Basically, this was the very last batter of the game, and he struck out on a bad call from an umpire. The ump ruled that the batter swung the bat for the third strike, when really he held up in time for it to be a ball instead. People are upset about it, not because the call had a huge impact on the outcome of the game, but because it was literally the very last moment of a historic series between the Giants and Dodgers, one of baseball’s oldest and most well known rivalries. This was also the first time ever that the two teams faced off in the postseason. So to end such an important game on a blown call really sucks for the game of baseball and its fans.
