The Barry Hills-trained Redwood swooped late to take top honours in the Coutts Glorious Stakes (Group Three) at Goodwood.
Sent off at 7-1 having filled the runner-up spot in the Princess Of Wales's Stakes at Newmarket's July meeting, the four-year-old was settled at the rear of the field by the trainer's son, Michael.
While favourite Duncan came under pressure early in the straight before meeting interference, Redwood and Sri Putra moved up stylishly and it was the former who got the better of a tussle in the final furlong to score by a length and a half.
The winning jockey said: "He ran a very good race at Newmarket and he travelled a lot sweeter today. When he travels he's got a very good turn of foot.
"He's growing and improving with racing. He won the Feilden Stakes and ran in the Dante, where he had problems, so he had a long time off and it took us a while to get him back to top form. I think his best season is to come now."
Hills senior added: "He was my 300th Newmarket winner and now my 50th at Glorious Goodwood. He's always been a good horse, but he had some niggling problems last year and going over a mile and a half seems to have brought out the best in him.
"I'll have to discuss it with the Prince (Khalid Abdullah, owner) but there's the Canadian International to think about, there's a race in Turkey and they are quite keen to send him over to America at some point."
Jacqueline Quest, who was disqualified after finishing first past the post in the 1000 Guineas, was expected to play a leading role in the other Group Three race on the card, the Oak Tree Stakes, but after holding every chance she weakened into fifth.
After the victory of 16-1 shot Tropical Paradise, trained not too far up the road near Godalming by Peter Winkworth, assistant Anton Pearson said: "I thought Jacqueline Quest would be very hard to beat, but I couldn't believe her (Tropical Paradise's) price.
"She can go to stud now, but we've one or two ideas left first. She's much better on soft ground."
