Can American Pharoah pull off the Triple Crown?

American Pharoah will run for the Triple Crown tomorrow at the Belmont Stakes, a prize no horse has won in 37 years.

If the Kentucky Derby and Preakness winner can finish the job, it will give the sport a much-needed boost.

Riding a six-race win streak, American Pharoah is undefeated this year. On Saturday, he will start from a favorable position at the number five gate, and is the pick to win at 3-5 odds. But the Belmont is also the toughest of the Triple Crown races and history may be stacked against him.

American Pharoah struggled early in the Kentucky Derby, but managed to pull it off in the end.

He had a much easier time at the Preakness, which he led virtually from the start. Now, American Pharoah must conquer Belmont. At 1.5 miles, the "Test of the Champion" is the longest of the Triple Crown events

"If he puts his ears up and he's doing easily, that's his signature move," American Pharoah's owner Justin Zayat said. "Right when he puts his ears up, and he starts looking around, he's alert, he looks like he's just having fun."

Affirmed was the last Triple Crown winner in 1978. Since then, 13 thoroughbreds have won the Kentucky Derby and the Preakness, only to lose the Belmont.

Trainer Bob Baffert has tasted that disappointment three times in his Hall of Fame career. American Pharoah, he says, is special.

"I've had some really great horses," Baffert said. "But nobody moves like he does."

Jockey Victor Espinoza is making his third run at the Triple Crown.

"A lot of times, they don't get much credit, the jockeys," Espinoza said. "But a lot of the times, it's always the jockey's fault."

American Pharoah's rivals will be gunning for him. Some skipped the Preakness and are well rested. Materiality and Frosted both train at Belmont Park and have home-track advantage.

"It feels like a championship boxing match," Yahoo! Sports writer Pat Forde said. "It feels like an NBA Finals game, an NFL playoff game. It will be a great, great atmosphere Saturday."

The winner of the Belmont gets a $1.5 million prize. American Pharoah's team says he's had great workouts this week, and doesn't seem to be suffering from the tight race schedule. If he wins the Triple Crown, Zayat says he will be retired and then collect some hefty stud fees.
