A tilt at the Melbourne Cup could be on the agenda for Ahzeemah after he clinched a deserved victory in a thrilling climax to the Lonsdale Cup at York.

The Godolphin runner had not finished out of the first two places in his past nine starts, but six of those efforts ended in defeat.

The Willie Mullins-trained Simenon was the 15-8 favourite after running Estimate close in the Gold Cup at Royal Ascot and dictated matters from the outset under a positive ride from Johnny Murtagh.

The six-year-old managed to shake off all of his opponents bar one, with Saeed bin Suroor's 4-1 shot Ahzeemah and Silvestre de Sousa wearing him down to prevail by a head following a titanic tussle.

"He's so honest and incredibly genuine," Godolphin racing manager Simon Crisford said.

"Hopefully the Melbourne Cup (could be an option), or the Qipco stayers' race on Champions Day at Ascot (October 19)."

Mullins remains keen on a trip to Australia with Simenon but he is not yet certain to make the final field for the Melbourne Cup.

"He's entered in the Prix du Cadran at Longchamp (October 6) and all those sorts of races, but if we think we'll get in it is still my intention to head south (to Australia)," Mullins said."

Ahzeemah's triumph proved the highlight of a magnificent treble for Godolphin and De Sousa.
