A total of 10 runners are due to go to the start in the Boylesports Ulster Derby.
The Donnacha O'Brien-trained Emperor Of The Sun shoulders top weight but the lightly raced son of super sire Galileo has run only four times, winning his maiden at Galway last season and holds an entry in the Irish St Leger, while the trainer/rider duo were in double form at Leopardstown yesterday.
Trainer Ger Lyons is doubly represented by Marchons Ensemble - owned by former top jump jockey, Graham Bradley, a long-time friend of the trainer from his riding days in Britain - and Baby Zeus.
Johnny Murtagh also is doubly represented with Red Kelly - a lightly raced horse who opened his account earlier this month at Leopardstown - along with Springbank, again a winner last time.
Aesop also won his maiden at the Foxrock venue on his last start and is trained by Jessica Harrington, who said: "He's a nice horse but was very big and backward last year as a two-year-old but has improved and won on his seasonal debut. I'm looking forward to him."
Caledon-based trainer Andy Oliver, successful with Shake A Leg last night at Leopardstown, provides a local runner with Silvertown - a winner on his penultimate start.
The Andrew Slattery-trained Sunchart has a similar profile to the majority of runners but is second best on ratings. The maidens are excluded from consideration but the truncated season has allowed very limited opportunities for the three-year-olds to highlight their ability.
Baby Zeus is taken to deny Emperor Of The Sun and Aesop in a very open affair and supply Ger Lyons with his second victory in the race following a shock success with Green Lassy in 2004 when Padraig Beggy was aboard - the jockey enjoying his biggest success when causing another shock partnering Wings Of Eagle (40/1) to victory in the Epsom Derby in 2017.
Meanwhile, the Ulster Oaks is the supporting feature and, yet again, an open affair.
Wilderness - winner of her last three starts - Too soon To Panic, Blackcatblackkitten, Brinjal and the Aidan O'Brien- trained Elizabethofaragon, a winner last time, form the short list. Brinjal remains a maiden and Blackcatblackkitten, with Declan Mc Donagh aboard the Joseph O'Brien-trained filly, is preferred with Too Soon To Panic the danger in view of the weight allowance for three-year-olds in the contest at present.
Grammata was considered good enough to contest the Queen Mary Stakes at Royal Ascot and, along with Miss Amulet, Measure Of Magic, Dacesa and Logo Hunter, make most appeal in the opener.
Trainer Eddie Lynam has landed the five furlong sprint for the past three years and is represented by Earls carrying top weight in today's renewal. Musical Rue, Sir Dotti and Sebs Star make more appeal.
She's Our Queen, Fictitious Lady and Toora Loora with the benefit of good draws appeal in the EBF Maiden, while Dermot Weld, who once dominated the Derby, meeting running debutante, Sharliyka. Toora Loora can continue trainer Harrington's runs of success.
Shumaker scored at Ballinrobe on Monday for Dundrod trainer Paul Trainer and turns out again in the 45/65 rated handicap with top apprentice Joey Sheridan again aboard. Noble Intention, trained by Tony Martin and top apprentice Dylan Mc Gonagle in the saddle, could spoil a repeat.
Shane Foley currently tops the jockeys championship with 40 winners and is a notable booking for Amiad. The Weld-trained Classify is taken to deny Oh so True and Lady Hanson in the finale.
Ulster Derby prediction: 1st Baby Zeus, 2nd Emperor of the Sun, 3rd Aesop.
Selections: 1.00 Dacesa 1.30 Sebs Star 2.00 Toora Loora 2.35 Blackcatblackkitten 3.10 Noble Intention 3.45 Baby Zeus 4.20 Classify
