RACING/News and preview: Aidan O'Brien's Group One year has been relatively unimpressive to date but there is the real potential for that to turn right around this weekend.

The enigmatic One Cool Cat is rated a 3 to 1 favourite to win Saturday's Haydock Sprint Cup despite the likelihood of having to face the likes of the Maurice du Gheest winner Somnus and the July Cup heroine Frizzante.

O'Brien, and jockey Jamie Spencer, won't finish there however as they can also look forward to the star juvenile filly Silk And Scarlet who is also likely to head the market in Sunday's Moyglare Stud Stakes at the Curragh.

That has been a successful hunting ground for O'Brien, who will be hunting a fourth Moyglare victory in five years with Silk And Scarlet.

The latter won the Group Two Debutante Stakes over the course and distance on her last start and that race was also the springboard to Moyglare success last year by Necklace.

British-trained fillies have won the Moyglare only twice in the last 10 years but Richard Hannon, who won with Lemon Souffle in 1993, could head the overseas challenge with the Cherry Hinton Stakes winner Jewel In The Sand.

Only Powerscourt has scored at the top level for Ballydoyle this year and Jamie Spencer will be anxious to make up for lost time having been controversially disqualified from the Arlington Million earlier in the month.

This afternoon's local action is at Downpatrick where Dermot Weld can provide the ideal bank holiday Monday kick-off to punters with Le Leopard in the maiden hurdle.

The best of this one's two hurdles starts to date was a third to Babble On in Ballinrobe in May but Paul Carberry's mount should be capable of much better on the evidence of his two most recent races on the flat.

They included a second in the GPT at Galway and on the forecast "good" going Le Leopard looks up to beating the 97-rated Another Deckie.

Weld has a spectacular record in the mile and a half conditions race having won it for the past five years but Tanwir doesn't look up to keeping the streak going and John Oxx's Sportsticketing looks a better option.

The filly has something to find on ratings with Imoya but Sportsticketing is clearly on the upgrade having danced up on the course and distance by 14 lengths on her last start.

The Wexford winner Chain could be the one in the Ulster Cesarewitch.
