Jhonny Gonzalez def. Abner Mares, KO Round 1 2:55

Words can not describe the shock of this win. Abner Mares, a man on the pound for pound list, an undefeated fighter who looked to be seriously on the rise, KO'd in just 1 round by the completely overlooked Jhonny Gonzalez. After 2 minutes of a feeling out process, Gonzalez used a perfect left hook to drop the heavy favorite Mares, sending the champion crashing to the mat. Mares struggled back to his feet, but was clearly hurt, and within a few more seconds, he was back on his back and the fight was wisely waved off.

At this point, you can pretty much close the books on any Upset of the Year award in boxing. Adonis Stevenson's KO of Chad Dawson was impressive, but it doesn't hold a candle to this. Just an incredible moment.
