Diamond Necklace (St Mark's Basilica) and Precise (Starspangledbanner), both Group 1-winning juveniles trained by Aidan O'Brien, headline 53 entries for the Betfred Oaks at Epsom on Friday, June 5.Unbeaten in three starts as a two-year-old, Diamond Necklace was last seen winning the Prix Marcel Boussac at ParisLongchamp, while Precise rattled off four consecutive victories as a two-year-old after being beaten on her debut at Fairyhouse, culminating with back-to-back Group 1 wins in the Moyglare Stud Stakes and Fillies' Mile.In total, O'Brien has entered 15 fillies in his quest for a 12th triumph in the Oaks, which would put him just one behind Robert Robson, the most successful trainer in the history of the Classic with 13 winners. O'Brien's other notable entries include Leopardstown maiden scorer Amelia Earhart (Camelot), who is one of four fillies currently trading at 8/1 at the head of Betfred's ante-post market.Joining Amelia Earhart, Diamond Necklace and Precise at 8/1 is Charlie Appleby's Abashiri (Frankel), a four-length winner on her debut at Kempton in November. Abashiri is joined in the home team by the likes of Legacy Link (Dubawi), who was last seen finishing fourth in the Fillies' Mile for John and Thady Gosden, and the William Haggas-trained My Ophelia (Wootton Bassett), who kicked off her career in style when winning a novice at Newbury in October.In addition to the Ballydoyle contingent, Robson Aguiar's unbeaten Blanc De Blanc (Not This Time) features among 11 other entries from Ireland, while Francis Graffard leads the international challenge with a pair of fillies in contention from his Chantilly base. They include Juddmonte's Gilded Prize (Frankel), who is unbeaten in two starts on the all-weather at Chantilly, and the Aga Khan Studs contender Behrayna (Sea The Moon), who made a winning debut at ParisLongchamp on Sunday.Graffard A-listers among 27 Coronation Cup entriesGraffard is also responsible for a pair of star names who could be in action at Epsom on Saturday, June 6, with Calandagan (Gleneagles) and Daryz (Sea The Stars) both featuring among 27 entries received for the G1 Coolmore Coronation Cup, which this year offers increased prize-money of £1 million.Calandagan, who was crowned Longines World's Best Racehorse for 2025, has won five times at the top level since being beaten by Jan Brueghel (Galileo) in last year's Coronation Cup, including when returning from four months off with a decisive win in the Dubai Sheema Classic at Meydan. Daryz, meanwhile, has been off the track since ending his three-year-old campaign with a narrow defeat of last year's Oaks heroine Minnie Hauk (Frankel) in the G1 Prix de l'Arc de Triomphe.Jan Brueghel and Minnie Hauk are both in contention to return to Epsom after their 2025 heroics, along with their stablemate Lambourn (Australia), who made it a clean sweep of the Group 1 races at this meeting for Ballydoyle when running away with the Derby. Completing the quartet of entries for Aidan O'Brien is Illinois (Galileo), who occupied the runner-up spot in both the G1 Gold Cup and G1 Goodwood Cup in 2025.Graffard's own four-strong contingent is completed by the multiple Group 1 hero Goliath (Adlerflug) and last year's G1 Prix Ganay second Map Of Stars (Sea The Stars), while Christophe Ferland's Aventure (Sea The Stars), the winner of the G1 Prix Vermeille, could also make the journey over from France.Other notable entries include last year's G1 Champion Stakes third Almaqam (Lope De Vega) and Juddmonte's high-class older mare Kalpana (Study Of Man), along with the progressive four-year-olds Bay City Roller (New Bay) and Convergent (Fascinating Rock).The post Diamond Necklace and Precise Among 53 Betfred Oaks Entries appeared first on TDN | Thoroughbred Daily News | Horse Racing News, Results and Video | Thoroughbred Breeding and Auctions.
