American Pharoah is the talk of the town after a win at Belmont made the horse the first Triple Crown winner since 1978. American Pharoah's accomplishments have landed him in the horse racing history books, but it's his jockey, Victor Espinoza, who deserves high praise today after announcing he would donate all his winnings to charity.

Espinoza, who was raised in a poor family in Mexico, has always given a portion of his earnings to charity. His charity of choice is City of Hope, a California-based cancer research and treatment center. According to the organization's website, he is a frequent visitor at the center, stopping by to share "smiles, gifts and stories." 

But after his recent Triple Crown win, Espinoza announced that he would donate all of his proceeds to the cancer center. In an interview after the race, he told reporters, "I won the Triple Crown right now, but I don't make any money because I'm donating all the money to the City of Hope."

The Triple Crown is comprised of three horse races — the Kentucky Derby, the Preakness Stakes and the Belmont Stakes. For a horse to win all three of these races in one season is considered the ultimate achievement in thoroughbred racing, which is why no horse has accomplished the task in 37 years. But that streak was broken over the weekend when American Pharoah and Espinoza won Belmont. 

And no one is more grateful or excited than the employees of City of Hope.

City of Hope, which also helps patients with diabetes and HIV, said in a statement: "City of Hope is deeply grateful for the support of Victor Espinoza and for his continuing efforts to raise awareness of our groundbreaking scientific research and our lifesaving, patient-focused care. We are extremely pleased to be able to congratulate him and American Pharoah for their remarkable accomplishment in winning the Triple Crown."
