Theyskens' Theory is being considered for a Grade One event in New York next month after she returned to form at Sandown last weekend.

The filly, who has an American pedigree and is owned by US fashion high-flyer Andrew Rosen, has competed in her home nation before when sixth in last year's Breeders' Cup Juvenile Fillies.

Theyskens' Theory, who is trained by Brian Meehan at Manton, took a Listed race at York in impressive style before an inferior display in the Coronation Stakes at Royal Ascot.

But she was back on song in last Saturday's De Vere Venues Atalanta Stakes.

Meehan said: "Theyskens' Theory is very well after her win and she may possibly next run in Belmont Park in the Garden City Stakes on September 17."

“She is also entered in the Kingdom Of Bahrain Sun Chariot Stakes at Newmarket later in September.”

Last year's Ebor winner Dirar begins an American adventure as a jumper in New York on Thursdaywith a start in the New York Writers Club Chase at Saratoga.

Barry Geraghty has been enlisted by trainer Gordon Elliott to take the mount in the valuable handicap event over just under two and a half miles.

Dirar has been pencilled in for other US targets in the autumn with plans to extend the gelding's stay until the Far Hills meeting on October 22 - an historic and hugely popular event in the New Jersey countryside.

Dirar, who has raced on the Flat this year, has proved himself a decent jumper and was third in last month's Galway Hurdle.

Elliott has had runner in the US before without success.

"He travelled over nicely and seems in good order. It's great to have Barry on our side for the race and the plan is to finish up at Far Hills in October,” Elliott said.

“We might run him once or twice in between."
