Frankie Dettori turns to Coronet in St Leger at Doncaster

Frankie Dettori has elected to ride Coronet over better-fancied stablemate Stradivarius in the William Hill St Leger at Doncaster on Saturday.

Trainer John Gosden has four Leger wins to Dettori's five and is again expected to play a leading role on Town Moor, with Coronet, last time finishing second to the yard's brilliant Enable in the Yorkshire Oaks, joined by Royal Ascot winner Stradivarius.
