If you missed Juan Manuel Marquez's breathtaking knockout of Manny Pacquiao tonight from the MGM Grand Garden Arena in Las Vegas, here's the right hand shot that finished it all:

You cannot time a counter right hand better than that, catch a guy harder than that, or sell out more on one perfect punch than that. It was without question the Knockout of the Year for 2012.

This was perhaps the end to the greatest modern rivalry in boxing -- or they could do it again a fifth time next year. Anything is open after this. It's hard to imagine boxing fans passing on a fifth fight after this incredible bout. There were doubts about the fight going in, but they ended quickly. This was a very, very special night for the sport of boxing. I doubt anyone who watched live will forget what they saw.
