Sunday promises a packed schedule of top‑class racing across three venues – Brighton, Worcester and the French classic meeting at Deauville – all streamed live on Sky Sports Racing. The centerpiece of the day is undoubtedly the Group One Sumbe Prix Jean et Louis Romanet, where the unbeaten three‑year‑old filly Diamond Necklace will take the lead in a glittering field of the best fillies and mares in Europe. Diamond Necklace, trained by Aidan O'Brien, has been a revelation since her debut.
She has now amassed six victories, four of them at the highest Group One level, and most recently she dominated the Nassau Stakes at Goodwood in a fashion that left little doubt about her class. Going back to the starting gate in Deauville, she will be racing against older horses for the first time this season, and the betting public will be eager to see if she can extend her unbeaten run to seven straight wins.
Her impeccable record, combined with the expertise of the O'Brien stable, makes her the clear favorite, but the field is deep enough to keep the outcome uncertain. Among the challengers, Joseph O'Brien’s Rebel Moon, piloted by jockey Dylan Browne‑McMonagle, offers a lively alternative.
Rebel Moon impressed in the Irish Oaks when she finished a respectable fourth, suggesting that she possesses the stamina and turn of foot required for the 2,000‑metre distance of the Sumbe Prix. If she can find a stronger rhythm and settle into the race, she could well be a serious threat to the favorite. Christophe Ferland’s Aventure, the winner of last year’s Prix Vermeille, also merits serious consideration.
Although she appeared slightly off‑form in her recent run behind Calandagan at Saint‑Cloud, Aventure’s Group Two victory in May demonstrated that she can still produce a high‑class performance when fully fit. If she returns to her best condition, she could pose the biggest danger to Diamond Necklace’s unbeaten streak. The rest of the field is rounded out by Red Letter, who is currently rated as the best of the remaining contenders.
While she may not have the same level of accolades as the top three, her consistent form makes her a solid each‑way candidate for punters looking for value. The Sumbe Prix Morny, another Group One contest on the same card, will also be a highlight.
The sprint over 1,200 metres will feature eight runners, including Orthodox and Man’s Best Friend, both of whom have shown considerable promise in recent outings. Aidan O'Brien will have three runners in this race, with Man’s Best Friend being the most fancied. Trained by O'Brien and ridden by the experienced Ryan Moore, the colt has progressed rapidly: after a modest fourth place on debut, he claimed a maiden at Naas, then stepped up to win the Group Two Richmond Stakes at Goodwood.
That trajectory suggests he could be on the cusp of a breakthrough at the highest level. Great Barrier Reef, a colt who captured the Coventry Stakes at Royal Ascot earlier in the season, suffered a setback after his Group One triumph and will be closely watched by the betting markets. If he can recapture his previous form, he could be a dark horse in the sprint.
Orthodox, the Norfolk Stakes winner, is another intriguing prospect for trainer Clive Cox. The horse displayed a blistering turn of speed over five furlongs, and the extra distance to six furlongs at Deauville should suit his natural sprinting ability without presenting a major test of stamina.
Senorita Bonita, who out‑finished Libertango at Newmarket in her most recent start, will also be on the card. With Libertango having secured a win at York earlier in the week, Senorita Bonita’s recent performance suggests she is in good form and could be a factor in the middle distances. The Brighton Summer Series Final will provide a fiercely competitive climax to the British portion of the day. The Blackmore Equestrian Construction Handicap, scheduled for 3.50 pm, will see a strong field of seasoned runners.
Among them, Arnaz, representing trainer Mark Loughnane and ridden by his son Billy, arrives in high spirits after two successive victories at Chepstow. His confidence and recent form make him a horse to watch in the warmer conditions expected later in the afternoon.
Other notable entries in the Brighton handicap include Diomed Spirit and Big Time Rascal, both of whom have previously won the race and will be offered at each‑way odds. Prefer The Sister, carrying the top weight, has shown a penchant for front‑running, having led the field in each of her last five starts, and will be a key factor in the early pace.
In addition to the headline races, the card features several Group Two contests that deserve attention. At 12.58 pm, the Prix du Calvados will see Dee’s Funny Girl, trained by Donnacha O’Brien, take to the track. Later, at 1.33 pm, the Prix Kergorlay will feature Santorini Star, a popular choice among punters, with Joseph O’Brien also represented in the field.
