Arabian Queen, a 44-1 shot in North American parimutuel betting, shocked the previously unbeaten Golden Horn on Wednesday in the Group 1 Juddmonte International at York Racecourse, turning back the Epsom Derby winner by a head. Racing over rain-softened ground, Golden Horn failed to show his best while starting for the first time since he won the Eclipse Stakes on July 4. Golden Horn was scratched from the King George VI and Queen Elizabeth Stakes because of a wet course, and both trainer John Gosden and jockey Frankie Dettori said the colt’s early- and mid-race keenness cost him at the end of the International. Golden Horn’s pacemaker, Dick Doughtywylie, opened a big lead after breaking slowly, with Arabian Queen tracking in second and Golden Horn tugging hard on the reins while racing in behind the top two. Turning into the four-furlong homestretch, Dettori still had a hold of his mount, and when he asked for run about three furlongs out, Golden Horn gave it to him. Arabian Queen had put away Dick Doughtywylie, and though she braced for the favorite’s challenge, Golden Horn out a head in front about a furlong out, nearly all who watched presumably assumed that he would push past and on to victory. But Arabian Queen had other ideas. The 3-year-old filly, who had never won at the Group 1 level, responded to Silvestre De Sousa’s urgent exhortations, drawing back on even terms with Golden Horn and forging to the front a couple of strides before the finish to post the biggest Group 1 upset on the European flat this season. Trained by David Ellsworth for owner Jeff Smith, Arabian Queen, by Dubawi and out of the Barathea mare Barshiba, won for the fourth time in 11 starts while winning for the first time since June 5, when she captured the Group 3 Queen Elizabeth Stakes. Her time for one mile, two furlongs, and 88 yards on good-to-soft ground was a slow 2:09.72. By virtue of her victory, Arabian Queen earned a guaranteed spot, entry fees, and travel expenses for the Breeders' Cup Turf through the Breeders' Cup Win and You're In program. The Grey Gatsby could not quicken with Golden Horn but stayed on one-paced to finish third, 1 1/4 lengths in front of the heavily bet Time Test, who never picked up his pace. Golden Horn lost for the first time in six starts, and while he did not run poorly Wednesday, the International hardly was a legacy-building moment for a colt who had shown signs of being elite in an historical sense. There’s little doubt now that Golden Horn shows his best on faster going, and his connections must hope for dry conditions at the Prix de l’Arc de Triomphe, likely his career finale. But at least Golden Horn ran. Gleneagles, the very talented English 2000 Guineas winner, was scratched Wednesday morning because of the wet turf. If the ground is right, he could race instead in the Irish Champion Stakes. Ward goes bold in Nunthorpe Wesley Ward already has blazed a pioneering trail, winning races in England and France with U.S. shippers, and on Friday at York, he ventures into still more rarely traversed territory, starting the 2-year-old filly Acapulco against older male rivals in the Group 1 Nunthorpe Stakes. The twice-started Acapulco races for the first time since she trounced 19 foes June 17 in the Group 2 Queen Mary Stakes at Royal Ascot. As a 2-year-old filly, she gets a huge break in the weights, 139 to 112 pounds, from the older males in the five-furlong Nunthorpe. Heavily favored in antepost wagering, Acapulco – described by Ward as strong and mature beyond her raw age – could become the third 2-year-old and the second 2-year-old filly to win the Nunthorpe; the juvenile colt Kingsgate Native won in 2007, while the 2-year-old filly Lyric Fantasy won in 1992. Acapulco, with Irad Ortiz Jr. in to ride, breaks from post 4 in a 20-horse field. Her main rivals are Muthmir, Sole Power, and Mecca’s Angel. Storm The Stars stays up Storm The Stars scored a game half-length win over Bondi Beach in the Group 2 Great Voltigeur Stakes on the International undercard Wednesday at York, and stewards left his number up after conducting an inquiry when Storm The Stars and Pat Cosgrave drifted left in deep stretch, pushing Bondi Beach off his course. Second in the Irish Derby, Storm The Stars could be a principal in the St. Leger at Doncaster later this summer.
