Aidan O'Brien's exciting prospect Roderic O'Connor looks set to clash with Kevin Prendergast's Dunboyne Express in the Leopardstown 2,000 Guineas Trial Stakes on Sunday.
The Ballydoyle colt got closest to Henry Cecil's unbeaten Frankel in the Dewhurst last autumn before a raid to France saw him secure the Group One Criterium International at Saint-Cloud.
Among the potential opposition is Prendergast's Anglesey Stakes-winner Dunboyne Express. Prendergast, who has also entered Mawakef, indicated yesterday both his entries will work tomorrow morning before a decision is made.
Exodus and High Ruler add strength to O'Brien's hand, while A Word Apart, Cocozza, Imperial Rome and Whipless complete the list of possibles.
O'Brien's dual Group One winner Misty For Me appears among 21 entries for the Leopardstown 1,000 Guineas Trial Stakes.
The daughter of Galileo won the Moyglare Stud Stakes before tasting success in the Prix Marcel Boussac at Longchamp on Arc day. The three-year-old is one of five entries for Ballydoyle.
Meanwhile, Jeremy Noseda has been forced to rule the well-regarded Peter Martins out of the 2000 Guineas at Newmarket.
The once-raced Johannesburg colt has been off the track since his win in a Newmarket maiden in July, when he beat Colorado Gold under Frankie Dettori.
Noseda said: “Unfortunately Peter Martins has met with a setback. This will rule him out of a planned tilt at the 2000 Guineas.”
Noseda's charge had been as short as 16-1 in places for the first Classic of the season on April 30.
Sunshine Always did not enjoy much luck at Lingfield last time but compensation awaits at Kempton tonight.
Jemma Marshall had to sit and suffer aboard the five-year-old grey in the straight in February before getting a clear run all too late to make an impact.
Nevertheless, Sunshine Always finished strongly when he did see some space and it was a creditable effort after five months off.
He remains on the same mark of 70 here and could be well in for the skysports.com London Mile Qualifier.
