Libranno, under leading Goodwood jockey Richard Hughes, has taken the Tanqueray Richmond Stakes.
Recording his sixth success of the meeting, Hughes spurred the two-year-old on inside the final furlong to edge out the the William Haggas-trained The Paddyman by one and a quarter lengths.
Well backed at 4-1, Paddyman was looking strong coming to the closing stages, but Hughes dug deep to the delight of the packed grandstands, returning as a warm 5-4 favourite.
Hughes said: "I was trying to get him to relax and get him breathing early on, as for nearly a minute I couldn't feel his belly going.
"He jumped extremely fast and I let him go to the front, but in the last two furlongs he was gawping at everything.
"I think he kills horses off halfway through the race with his speed and then just grinds it out at the finish.
"He had a hard race the last day and a tough enough race today, but he's a decent horse and a fast horse."
When asked about a potential next port of call for the juvenile, Hughes added:
"Ideally something like the Prix Morny, but that might come a bit quick for him."
Trainer Richard Hannon said: "We took him to Newmarket very raw, but we still thought he'd have a good chance in the July Stakes and he's won very well again today.
"I don't really know what we're going to do with him now. It's up to the owner really, but he wouldn't want much further than six furlongs unless we can teach him to race in a different way."
