American Pharoah -- TRIPLE CROWN WINNER!!

He did it!!! American Pharoah became the first Triple Crown winner in 37 years by holding off the field to take the Belmont Stakes.

American Pharoah was heavily favored -- after winning the Kentucky Derby and The Preakness -- but we've seen this many, many, many times before -- and the Triple Crown hadn't been won since Affirmed in 1978.

AP, ridden by Victor Espinoza, was awesome -- leading the Belmont from wire to wire.

The horse is now the 13th horse to win the Triple Crown.

And if you haven't been paying attention to the sport -- yes, his name is a typo. And he still managed to win. Amazing!
