Thesecretadversary (3c St Mark’s Basilica - Too Soon To Panic, by Gleneagles) became a new Group 1 winner for St Mark’s Basilica with victory in the Prix Jean Prat at Deauville on Sunday. The Fozzy Stack-trained colt was a Listed winner at Tipperary last year and had already claimed two Group 3 successes this term in the Leopardstown 2,000 Guineas Trial and Jersey Stakes. Ridden by Christophe Soumillon, the Cayton Park Stud and Coolmore homebred made all against the near rail before increasing the tempo from two furlongs out. The colt kept on well inside the final furlong to score by half a length from 1,000 Guineas heroine True Love (by No Nay Never). Stack said: “That was great and we thought he would run well but we were taking on two Guineas winners which is tough, especially one away from home and another who doesn’t live too far from us. “It’s a great day and I would like to thank the Rupert and Magnier families for sending us this horse and his last two days have been unbelievable. “Seamie [Heffernan] spoke to Christophe earlier and told him about the horse and Christophe asked if I would mind if he made the running as there was no pace. I said don’t fight with him and just don’t get beat and he carried that out to perfection! “This horse has a great constitution and he’s very tough. Both Christophe and Seamie have said they see six furlongs as no problem and he’s getting quicker. For a horse we thought would get a mile and maybe a little bit with it, he’s getting quicker." He added: “We trained his grandmother [Scream Blue Murder] and she was a sprinter and a lot of the family have been sprinters so maybe he’s returning to type. “We’ll see how he comes out of this and get home and we’ll make a plan." Thesecretadversary is the second individual Group 1 winner from St Mark's Basilica's first crop, the other being unbeaten dual French Classic heroine Diamond Necklace.
