Timothy Bradley’s win over Juan Manuel Marquez to remain unbeaten and defend his welterweight title didn’t come easy, but it was a victory nonetheless.

On this day in 2013 at the Thomas & Mack Center, the American thwarted his Mexican opponent’s bid for a title in a fifth weight class at the age of 40 by earning a split decision result. Two judges scored it 116-112 and 115-113 for Bradley, while the third had Marquez winning 115-113.

The biggest punch of the night came in the final seconds of the final round, when Bradley connected with a crunching left hook to send Marquez staggering backwards. The pro-Marquez crowd though serenaded Bradley with boos.
