LAH Ti Dar made hard work of it before ultimately landing the odds in the Al Basti Equiworld Dubai Middleton Fillies’ Stakes at York.
The St Leger runner-up was stepping down to a mile and a quarter for the first time in 12 months and the 1/3 shot needed every yard to take the Group 2 honours.
Queen Of Time set an honest pace until the straight, where the tempo increased and the race hotted up.
Frankie Dettori appeared to be confident enough on Lah Ti Dar – but he had to roust the John Gosden-trained filly to see off the persistent challenge of Sir Michael Stoute’s Rawdaa by a neck.
Stoute’s other runner, Sun Maiden, was third after looking menacing two furlongs out.
