Ashroe Diamond showed her class to provide Willie Mullins with a third victory in the SBK Yorkshire Rose Mares’ Hurdle at Doncaster on Saturday.

The Closutton handler had sent two of his best ever mares to Town Moor to plunder this Grade Two prize in the last decade, with the brilliant Champion Hurdle heroine Annie Power triumphant in 2014 and Vroum Vroum Mag landing short odds three years later.

This time around Mullins fired a twin assault, with 7/4 shot Ashroe Diamond considered the second string by punters as her stablemate Gala Marceau was sent off the 10/11 favourite.

Both had shown their worth at Grade 1 level, with Gala Marceau beating another Mullins mare in Lossiemouth at Leopardstown last year before the tables were turned in the Triumph Hurdle, while Ashroe Diamond was placed behind top-class geldings Facile Vega and Marine Nationale before enjoying her day in the sun at Fairyhouse in the spring.

Crucially, Ashroe Diamond had already run this winter with a third-placed finish in the Hatton’s Grace, whereas Gala Marceau had been off the track since doubling her top-level tally at Auteuil in May.

It was clear earlier in the home straight the former was travelling the better in the hands of the trainer’s son Patrick Mullins and once given the office, Ashroe Diamond picked up smartly to put the race to bed and score by two and a half lengths from the staying-on Under Control.

“What more could you ask for? I think my mare’s form with Facile Vega and Marine Nationale is the best mares’ form out there,” said Mullins junior, riding his first ever winner at Doncaster.

“She has a high cruising speed and she settled great today, she’s normally quite keen and you have to get a bit of cover with her.

“She’s always a brilliant jumper and she can often run a bit keen, but she has form against top geldings last year and I always rate that above juvenile form – that’s a restricted division.”

Ashroe Diamond was widely cut for the Mares’ Hurdle at the Cheltenham Festival in March and Mullins views her as a leading candidate.

He added: “Her pedigree suggests she can go further, but it’s two and a half miles in the mares’ race in March and that will be no problem to her.

“We won’t know until Cheltenham but I’d love to ride her there.”
