Fleeting Spirit came out on top in a dramatic renewal of the Darley July Cup at Newmarket.
Jeremy Noseda's filly travelled sweetly for substitute jockey Tom Queally but the problems started when she hit the front going into the dip.
Main Aim, who had cut out the pace, was beginning to stay on again but Ryan Moore had to snatch up which resulted in a stewards' inquiry, although the placings remained unaltered. J J The Jet Plane was third, while Paco Boy absolutely flew home into fourth.
Queally said: "When we jumped nobody was inclined to go on so as a result we've probably gone a shade slow in the early part. I gave her a crack on her right and she went left and then I pulled it through immediately and the opposite happened, but I was well on top near the end. She has a really impressive turn of foot."
Noseda added: "This wasn't really the original plan after Ascot but we gave her 10 days off and I thought I want to be around if for some reason Scenic Blast doesn't turn up. Then I gave her a piece of work last Wednesday and credit to the lad who rides her out as he said she'd come on an absolute bundle since Ascot.
"This is a Group One she deserves as I feel when my horses got sick just before Ascot last year that she was robbed of winning the King's Stand. She never really bounced back for the rest of the year but today was a great result and a great performance."
