His Highness Sheikh Hamdan bin Mohammed bin Rashid Al Maktoum has donated his Dubai World Cup 2015 winnings to an autism charity.
He shared the news on Twitter on Sunday, following Saturday’s triumph with Prince Bishop, ridden by William Buick.
They won by two and three-quarter lengths on Saturday as the 12-1 outsider sprinted clear of California Chrome, the 2014 American Horse of the Year.
“I am pleased to announce that I have donated the Dubai World Cup prize of 6 million dollar to the Dubai Autism Centre,” he wrote on Twitter. “I am optimistic for what the Dubai Autism Centre will achieve socially and medically for children with autism.”
California Chrome, ridden by Victor Espinoza, was the 6-4 favourite to triumph in the world's richest horse race, but the Kentucky Derby and Preakness champion could only finish second, one and a quarter lengths ahead of Lea, piloted by Joel Rosario.
"He was slow away from the gate but we worked our way out down the back -- we had a lot of ground to make up," said jubilant jockey Buick. "He's a very tough horse. He's got a huge heart and gave me his all today."
Prince Bishop, trained by Godolphin's Saeed bin Suroor, completed the 2,000 metre contest in two minutes 03:24 seconds at the opulent 60,000-capacity Meydan racecourse. The full field of nine finished the race.
The eight-year-old gelding is owned by Dubai Crown Prince Sheikh Hamdan bin Mohammed Al Maktoum, whose other runner Long River trailed in seventh.
He tweeted after the race: “I am proud of Prince Bishop for winning the 2015 Dubai World Cup. I dedicate this win to the President, the Vice President, rulers and people of the UAE.. Congratulations to the UAE.”
Japan's Hokko Tarumae, with Hideaki Miyuki in the saddle, set the early running, but could not maintain that pace.
California Chrome was tucked in second and saw off the fading challenge of defending champion African Story, the Goldolphin-owned eight-year-old finishing a disappointing sixth, but had no response to Prince Bishop's charge.
"We brushed by him pretty quick," said Buick. "I went into the race thinking that he (California Chrome) could be a doubtful stayer so when I went I was going to stretch my horse and make him work and at the end of the day the best horse won."
