Godolphin jockey William Buick has hailed his victory aboard Masar in the Investec Derby at Epsom on Saturday as the greatest moment of his career to date.

Although the 29-year-old has tasted victory at the top level across the world, he has placed his success aboard the Charlie Appleby-trained son of New Approach at the top of the pile.

He said: “I would say it’s my biggest win. I’ve ridden in it a few times and come second a couple of times.

“Breeders’ Cup races are very big but the Derby there is something special about it.

“I think any horse person in the world, certainly this part of the world, would say it’s the race to win.

“I’ve ticked that box 100 per cent now and I want to tick it again.

“You can never rest on your laurels but in this sport you move on so quickly. You have to keep focused and keep your hunger up.

“To see Sheikh Mohammed and all the family so happy, for me personally, and for everyone involved, it meant a huge amount.”

He added: “It probably hasn’t quite sunk in, the magnitude of it and that it was the first blue colours of Godolphin to win it – and for me to be the jockey to deliver that success.”

Victory in the Group One prize was not just a long-held ambition for Buick, it was also a day that Masar’s groom Said Bahadar had been dreaming would come true for his pride and joy.

He said: “After he won the Derby I was over the moon. It was a dream come true that was the important thing.

“We felt he could win a big race but we now hope he can win the Irish Derby as well so we are crossing our fingers for that.”
