Unbeaten in two Group 3 stakes in October and January, the highly touted filly Enthaar will have her Group 1 debut in Saturday’s $1.16 million Blue Diamond Stakes for Southern Hemisphere 2-year-olds at Caulfield Racecourse in Melbourne, Australia. Enthaar won her debut in the Gimcrack Stakes at Royal Randwick Racecourse in October as the 3-5 favorite and followed with an easy 2 1/2-length win at 1-4 in the Chairman’s Stakes at Caulfield Racecourse on Jan. 30 in her lone start this calendar year. Enthaar will be favored in the Blue Diamond, though not as strongly as in her first two starts. Trained by Ciaron Maher and David Eustace, Enthaar is one of five fillies in a field of 16, a group that includes five other stakes winners - the males Anamoe, General Beau, and Ingratiating, and the fillies Arcaded and Dosh. Enthaar, by Written Tycoon, has won from a stalking position and by setting the pace in her brief career. Jockey Mark Zahra, who was aboard for the win on Jan. 30, has the mount in the Blue Diamond Stakes, which is part of an all-stakes, nine-race program. :: Get free past performances, analysis, and picks for Australian racing The Caulfield program begins at 10:40 p.m. Eastern, or 7:40 p.m. Pacific, on Friday. Wagering is available through DRFBets.com. General Beau, a colt by Brazen Beau, has won 3 of 4 starts for trainers Mathew Ellerton and Simon Zahra. General Beau has won two stakes for colts and geldings at Caulfield in the last month in the build up to Saturday’s race - the Blue Diamond Preview Stakes at five furlongs on Jan. 26 and the Group 3 Blue Diamond Prelude Stakes at 5 1/2 furlongs on Feb. 6. In the latter race, General Beau finished a nose in front of the fast-closing Anamoe, who will be fitted with blinkers for the first time in the Blue Diamond Stakes. The Caulfield program includes two other Group 1 sprints worth $387,950 - the Melbourne Futurity at seven furlongs and Oakleigh Plate at 5 1/2 furlongs. Behemoth will be favored in the Melbourne Futurity. A 5-year-old gelding who has won 8 of 19 starts, Behemoth has won four of his last five starts, all in stakes, since August, including two Group 1 races at seven furlongs at Caulfield in August and September. The winning streak was interrupted by a 10th-place finish in the $10.7 million Everest Stakes at Royal Randwick in October. Behemoth returned from a brief layoff in the Australian summer to win the Durbridge Stakes against five rivals at 5 1/2 furlongs at Morphettville Racecourse on Jan. 30. The brilliant mares Arcadia Queen and Probabeel, the winners of Group 1 races in October and November, pose the most significant threat to Behemoth. Of the two, Probabeel, the winner of the Group 1 Epsom Stakes at a mile on Oct. 3, may be slightly better suited to the distance of the Melbourne Futurity. The Oakleigh Plate will be the group stakes debut for Ancestry, who has won 8 of 13 starts, including the Century Stakes at five furlongs at Flemington Racecourse on Nov. 5 in his most recent start. Ancestry is part of a competitive field of 18 that includes Celebrity Queen, second in the Group 1 Winterbottom Stakes at six furlongs at Ascot Racecourse in Perth in November, and Anders, a 3-year-old colt who won a Group 3 at Rosehill Gardens in August, but was last of 14 in the Group 1 Coolmore Stud Stakes at six furlongs on Oct. 31. Anders is quick, and expected to set the pace in the Oakleigh.
