Fortune takes over on Delegator Delegator, runner-up in the 2,000 Guineas at Newmarket, will have a new jockey in the St James's Palace at Royal Ascot as Jimmy Fortune is to replace Jamie Spencer. Fortune rode the Brian Meehan-trained colt in his first two starts as a juvenile, although Spencer has been his regular partner since then, winning the Craven in great style before the pair found only Sea The Stars too good in the Guineas. Delegator got stuck in the mud in the Irish Guineas last time out, finishing eighth of the nine runners to Mastercraftsman, who was only fifth at Newmarket. "Jimmy has been booked for Delegator, obviously he's very pleased," said Fortune's agent, Tony Hind. Meehan believes Delegator has a "great chance" of landing his first Group One success in Tuesday's mile showpiece. "He has been working very well and is in great form. We are very keen to run and, if the ground is right for him, he has a great chance. If conditions remain something like they are at Ascot now, he will definitely take his chance," he revealed on his website. Fortune said: "I'm delighted to come in for the ride, he's obviously a top-class colt and hopefully the ground will be more favourable for him than when he ran in Ireland." Delegator's owner Poilin Good said: "We just fancied a change and that's all it is. The horse worked very well this morning and it is now up to Brian whether he runs next week. Obviously the conditions were atrocious when he ran in Ireland but he doesn't seem to have suffered any ill effects from that race and we'll just have to see what happens." "You never know what can happen on the day as unfortunately we don't have a crystal ball but the horse is in good form. If it's firm ground, like it was at Newmarket, he might not run."
