Lah Ti Dar and Kew Gardens are among 12 horses declared for the William Hill St Leger at Doncaster on Saturday.
The John Gosden-trained Lah Ti Dar returned from an enforced injury absence with a scintillating display in the Galtres Stakes at York last month and the Clarehaven handler confirmed on Wednesday she would take on the boys in the season’s final Classic.
Lah Ti Dar disputes favouritism with Kew Gardens, who bids to provide trainer Aidan O’Brien with a sixth St Leger success.
The Galileo colt won the Queen’s Vase at Royal Ascot and the Grand Prix de Paris earlier this summer before finishing third under a Group One penalty in the Great Voltigeur at York.
The Ballydoyle handler also saddles Nelson, Southern France, The Pentagon and Zabriskie.
Great Voltigeur winner Old Persian is one of two runners for Charlie Appleby after the Newmarket handler confirmed Loxley will also take his chance.
Loxley finished second in the Bahrain Trophy in July but has since won twice in France impressively.
He had been under consideration for the Prix Niel this weekend but will instead stay closer to home.
Appleby is currently at the sales in Keeneland, but confirmed to www.godolphin.com: “We have decided to run two in the Leger — Old Persian will be ridden by William Buick, while James Doyle will be on Loxley.”
Lah Ti Dar is one of two fillies in the race along with the supplemented Maid Up from Andrew Balding’s yard.
Mark Johnston saddles Investec Derby runner-up Dee Ex Bee, Raymond Tusk represents Richard Hannon and the Tom Dascombe-trained Proschema completes the line-up.
