Mustashry made a successful return from a lengthy absence in the Davies Insurance Services Gala Stakes at Sandown.
Sir Michael Stoute’s charge won the Group Three Strensall Stakes at York last August, but finished down the field in the Joel Stakes at Newmarket the following month and had been off the track since.
The five-year-old was an 11-4 chance for his comeback in this Listed contest and was always travelling strongly in the hands of Jim Crowley.
The admirable Big Country put up a typically determined effort from the front under Ryan Moore, but was claimed by Mustashry inside the final furlong and the Hamdan Al Maktoum-owned gelding had enough in reserve to hold the strong-finishing Spark Plug at bay by half a length.
Big Country boxed on for third with 7-4 favourite Euginio only fourth.
Richard Hills, assistant racing manager to the winning owner, said: “We gelded him as he had a few problems and that has just helped him along. He is from a really good family. They try hard.
“This horse has not done a lot wrong and he is still with Sir Michael Stoute, which is a good sign.
“We will see how he comes out of this and talk with Sir Michael and the boss and work away.
“He likes fast ground. He has never been a horse that acts on soft ground.”
