Sunday promises a packed schedule of thoroughbred action across three venues – Brighton, Worcester and the French resort of Deauville – all streamed live on Sky Sports Racing. The centerpiece of the day will be the Group One Sumbe Prix Jean et Louis Romanet, where the brilliant three‑year‑old filly Diamond Necklace will head a world‑class field.
Diamond Necklace, trained by the legendary Aidan O'Brien, arrives at Deauville unbeaten in six starts, four of which have come at the highest level. She most recently dominated the Nassau Stakes at Goodwood, a performance that underscored her ability to take on older mares and fillies. With that victory added to her record, she will be aiming for a seventh consecutive win and a second Group One triumph, a feat that would cement her status as one of the season's standout performers.
Joseph O'Brien’s filly Rebel Moon also merits close attention. Ridden by Dylan Browne‑McMonagle, the filly impressed when she finished fourth in the Irish Oaks, suggesting that she possesses the stamina and class to challenge for the prize. While she may not yet have a win at this level, her recent form hints at the possibility of a breakthrough performance on the day.
Aventure, the 2023 Prix Vermeille champion, is another serious contender for Christophe Ferland’s stable. Although she appeared to be off‑colour in her recent run behind Calandagan at Saint‑Cloud, her Group Two victory in May demonstrated her ability to deliver when it matters. If she can rediscover that earlier form, she could be the primary threat to Diamond Necklace’s bid for dominance.
Red Letter, a consistent performer in the European circuit, is rated as the best of the remaining runners and will likely feature prominently in the betting markets. The day will also feature a thrilling renewal of the Sumbe Prix Morny, a sprint race that will see eight juveniles compete for glory. Among them, Orthodox and Man’s Best Friend stand out as the leading prospects. Man’s Best Friend, trained by Aidan O'Brien and piloted by Ryan Moore, has shown rapid progression.
After a modest fourth‑place debut, the colt claimed a maiden at Naas before stepping up to win the Group Two Richmond Stakes at Goodwood. That upward trajectory places him among the most promising juveniles and suggests he could be a future star.
Great Barrier Reef, another O'Brien trainee, suffered a setback after his Coventry Stakes victory at Royal Ascot. While his recent form has been muted, the colt’s underlying ability means he will be closely watched by punters looking for a bounce‑back performance.
Orthodox, the Norfolk Stakes winner, is a fascinating prospect for trainer Clive Cox. The colt displayed a blistering turn of foot over five furlongs, and the step up to six furlongs in the Morny should suit his speed and stamina blend.
Senorita Bonita, who out‑finished Libertango at Newmarket in her last outing, adds depth to the field. With a recent win at York, she has shown she can handle a variety of track conditions and distances, making her a genuine threat. Beyond the headline races, Sky Sports Racing will also bring the Brighton Summer Series Final to viewers, featuring the Blackmore Equestrian Construction Handicap at 3.50 pm.
Arnaz, representing Mark Loughnane and ridden by his son Billy, arrives in good spirits after two victories at Chepstow and will be a key contender in the warmer conditions expected later in the day. Other notable entries include Diomed Spirit and Big Time Rascal, both previous winners who will be offered each‑way odds, and top‑weight Prefer The Sister, who has led the field in her last five starts and commands respect for her consistency. The broadcast will also highlight the Group Two Prix du Calvados at Deauville, where Dee’s Funny Girl, trained by Donnacha O’Brien, will take to the course, and the Group Two Prix Kergorlay, featuring Santorini Star, a popular pick who will be ridden by Joseph O’Brien.
Finally, back in England, the Sea Suite will lead the Class Four field at Brighton, providing a solid conclusion to a day filled with high‑calibre competition.
