Mars bids to lift the spirits of the Aidan O'Brien stable in the Jockey Club Of Turkey Meld Stakes at Leopardstown.
The Ballydoyle team were dealt a big blow by the serious injury to St Nicholas Abbey, and Mars will have plenty of supporters now that he is dropped in class following sterling efforts in the 2000 Guineas, Derby, St James's Palace Stakes and Eclipse.
Heading the opposition is Scintillula, who backs up just five days after finishing fourth in the Irish Oaks, with Elleval, La Collina and Along Came Casey also capable of making an impact.
O'Brien applies blinkers to Sir John Hawkins in an attempt to banish a slightly disappointing July Stakes performance to the memory in the Korean Racing Authority Tyros Stakes.
He is joined in the Group Three line-up by stable companion Expedition, while Ger Lyons should have high hopes for Exogenesis, who supplemented a Fairyhouse success when his sights were raised at this venue earlier in the month.
Heirloom made it third-time lucky at Dundalk recently and is another strong chance for O'Brien in the kieranoconellracing.com Anniversary Handicap.
Jim Bolger pitched Feile Na Mban into Listed company for her introduction and she ran with plenty of credit behind Irish Oaks runner-up Venus De Milo, so it will take a decent one to beat her in the Irish Stallion Farms EBF Maiden for older horses.
Zelie Martin so nearly made a successful handicap debut for the Coolcullen handler at Navan and she tries to go one better off a 5lb higher rating in the Morocco SOREC Handicap.
Stablemate Neophilia failed in a hat-trick bid last week but plenty will keep the faith in the Ash Apprentice Handicap.
Tahaany was third to subsequent Group Three runner-up Perhaps last time and a similar level of performance may be enough to see her home in the opening Irish Stallion Farms EBF Maiden at 5.45.
