The 21-year-old gave the girls’ team a flying start as she delivered the Clive Cox-trained sprinter with a well-timed challenge in the final furlong, after El Astronaute and Watchable had set the early pace.
While that pair could not keep up the gallop at the business end of the five furlongs, Tis Marvellous (6-1) came with a rattling run to score by a length and a quarter from from Gracious John, with Doyle’s teammate Hayley Turner third on Line Of Reason.
Doyle said: “It’s a massive deal for me to get the call-up (to ride at the Shergar Cup), let alone have a winner.”
Cox said: “We did expect a big run last week (in the Stewards’ Cup at Godwoood), but it was the extreme temperature. He didn’t take on a lot of fluids.
“He was fifth in the Commonwealth Cup last year. He’s a high-class performer and he’s basically in a lower-grade race than he has been.”
