Treasure Beach, Carlton House, and Memphis Tennessee, respectively the second, third, and fourth-place finishers in the English Derby, renew their rivalry Sunday at The Curragh in the Group 1 Irish Derby. Treasure Beach and Memphis Tennessee are trained by Aidan O&rsquo;Brien, who also has Roderic O&rsquo;Connor and Seville in the eight-horse field. With half the runners, O&rsquo;Brien figures to have a solid chance of landing his sixth straight victory in the 1 1/2-mile Derby.\r\nCarlton House, on the other hand, will attempt to become the first English invader to win the Irish Derby in 17 years. Trained by Michael Stoute for Queen Elizabeth II, the British monarch, Carlton House was well supported to capture the English Derby after beating Seville in his prep for the race, the Dante Stakes, but Carlton House could do no better than a close third. It&rsquo;s possible his performance at Epsom fell short of his best, since Carlton House had suffered an injury scare earlier in the week and was not a certain runner during the Derby lead-up. With just four starts, Carlton House should have room to come forward, though he has yet to prove himself beyond 1 1/4 miles and will be tested for stamina through the long uphill homestretch at The Curragh.\r\nMemphis Tennessee may be more pacemaker than true contender, and Seville followed his Dante defeat with a 10th-place English Derby finish. Roderic O&rsquo;Connor is a course winner, having captured the Irish 2000 Guineas, but he was found wanting June 5 in the French Derby and may prove more adept at shorter distances. That leaves Treasure Beach, who took a tough loss at Epsom when nipped on the wire by Pour Moi. One race earlier, Treasure Beach won the Chester Vase at 1 1/2 miles over Nathaniel, a talented colt who came back to win the Group 2 King Edward Stakes last week at Royal Ascot by five lengths.\r\nDermot Weld-trained Notable Graduate has been first or second in all five of his starts and has won over 1 1/2 miles, but he will face far stronger competition Sunday than he&rsquo;s yet encountered. Native Khan was third to Frankel in the English 2000 Guineas before coming fifth in the Epsom Derby.\r\nSarafina tops Grand Prix de Saint-Cloud\r\nOnly five horses were left in Sunday&rsquo;s Group 1 Grand Prix de Saint-Cloud after the final declaration stage, a quintet headed by the 4-year-old filly Sarafina. Third in Workforce&rsquo;s 2010 Prix de l&rsquo;Arc d&rsquo;Triomphe, Sarafina, the 2010 French Oaks winner, finished second to the gold older horse Planteur in her 2011 debut before capturing the Prix Corrida at Saint Cloud in her most recent start. Sarafina, owned by the Aga Khan and trained by Alain de Royer Dupre, has yet to win beyond 1 5/16 miles and will be racing 1 1/2 miles Sunday.\r\nCirrus des Aigles was third behind second-place Sarafina in the Prix Ganay this spring, but appears to have come forward since then with a second to Goldikova and a last-out win at Longchamp.\r\nSilver Pond beat the decent Behkabad in the Grand Prix de Chantilly in his most recent start.\r\nThe Grand Prix de Saint-Cloud is a Win and You're In race for the Breeders' Cup Turf.
