Punchestown Report:There are only two British-trained runners at Punchestown today and the home team will be giving thanks for that after a cross-channel clean-sweep of yesterday's three Grade One features, including an unlikely success for Refinement in the €200,000 Dunboyne Castle Champion Stayers Hurdle.

The Jonjo O'Neill-trained mare, a Punchestown Grade One winner in 2005, carried Tony MCoy to a two-and-a-half-length defeat of Powerstation after taking advantage of a bad injury to the hot favourite Mighty Man before the second last.

Mighty Man broke down on his off-fore leg and had to be immediately pulled up by jockey Richard Johnson who had taken the horse into the lead from the start.

"I was niggling from four flights before that which I normally don't have to do because he's such a trier. He didn't want to pull up. He's so genuine he would have kept going," Johnson reported.

"You couldn't blame the ground or anything like that. It was something that could have happened at home."

Mighty Man was later taken to the nearby Anglesey Lodge Veterinary Clinic for attention to a tendon injury but his injuries are not believed to be life-threatening.

McCoy brought Refinement through from last to secure a 16 to 1 success and postpone a trip to stud for the mare who is owned by the Coolmore partner, and classic-winning owner, Michael Tabor.

"They might have a rethink about that now. I know if she was mine, she'd keep going for a while longer!" said Frank Berry who was representing the absent O'Neill and Tabor.

It later emerged that the Queen Alexandra Stakes at Royal Ascot is a target for Refinement.

The disappointment of the race was the former champion hurdler Brave Inca who looked beaten just after half-way and eventually struggled home in sixth.

"He was never going to win at any stage. He was never travelling. If he changed legs once, he changed them a hundred times," reported Ruby Walsh, while Colm Murphy added: "I wouldn't read too much into it. He's had a lot of hard races and that might have been one too many."

Ferdy Murphy and Graham Lee were robbed of a top-flight success on Tuesday when Aces Four fell at the last in the Ellier Chase but the giant Another Promise made no mistake in the Swordlestown Cup to beat his compatriot Royal Shakespeare.

"I'd say he's a Gold Cup horse. Potentially there's massive improvement there. He's 17.2 and only seven. Next year we'll up him in trip," Murphy said.

"He's a different type to Aces Four, maybe more suited to bigger tracks. But they're two good ones to have."

The favourite, Gemini Lucy, unseated jockey Andrew Leigh at the first fence.

The third Grade One success, and the fourth in total of the week for Britain, came when the favourite Punjabi overcame Financial Reward by three-parts of a length in the Ballymore Champion Four Year Old Hurdle.

"He deserved that. Katchit has been just too good for him but it is quite a brave little four-year-old that can run at Cheltenham and Aintree and then come here. On the ratings he had a big chance but these Grade Ones are never easy," said trainer Nicky Henderson.

Only a short head and an inspired ride by "Slippers" Madden deprived the visitors of a four-timer as the topweight American Jennie secured a short-head victory over Noir Et Vert in the Pat Taaffe Handicap Chase.

The biggest cheer of the day, however, came for Spot Thedifference's emotional success in the La Touche Cup as the 14-year old secured a 10th consecutive win in the banks feature for trainer Enda Bolger.

"I was worried at half-way in case he'd get too detached but four and a half miles is a long way and they had to slow down," beamed Bolger.

"He's a brilliant horse and having a good man on his back like John Thomas (McNamara) is a big help."

Favourite backers got off to a perfect start when Lord Killucan easily won the Bishopscourt Cup for the leading flat trainer Michael Halford.

"This was the plan for this horse since before Christmas. He really liked that good ground," said Halford who was unable to outline future plans. "I'll have to ask Enda Bolger where to go now because I'm lost!"

But there was bad news for punters in the bumper when the 20 to 1 outsider Meadow Vale beat the 33 to 1 shot Artic Tour by a head.
