Legendary Lunch held off the late surge of Danielsflyer to claim victory in the Investec Woodcote Stakes at Epsom.
A winner on his Windsor debut before being turned over at long odds-on at the same venue next time, Legendary Lunch was a 5-2 joint-favourite for the opener on Oaks day.
The chestnut colt was keen early on, but was given a nice lead into the straight and moved up to challenge for the lead with two furlongs to run.
Richard Hannon's charge looked set to win decisively after taking a couple of lengths out of the field, but the David Barron-trained Danielsflyer finished with a wet sail and there was just a nose between them at the line.
Sea Of Snow was third, with the other joint-favourite, Tibr, a shade disappointing in fifth.
Winning jockey Pat Dobbs said: "This horse has loads of speed and is a quick learner."
In the feature race of the day, Aidan O'Brien's Minding produced a phenomenal turn of pace to take the Investec Oaks under Ryan Moore.
Teak-tough veteran Tullius claimed a narrow victory after a pulsating three-way finish to the Investec Diomed Stakes.
With last year's winner Arod a late withdrawal on account of the rain-softened ground, the Andrew Balding-trained Tullius was the 5-2 favourite to secure an 11th career victory in the hands of regular partner Jimmy Fortune.
Custom Cut made much of the running in the eight-and-a-half-furlong Group Three and kicked from the home bend in an attempt to draw the sting out of his rivals.
However, the patiently-ridden pair of Tullius and Decorated Knight covered the move to set up a grandstand finish.
Custom Cut refused to bend, but was headed close home by both Tullius and Decorated Knight, with the former winning the argument by a short head.
The Stuart Williams-trained Examiner toughed out victory in the Investec Mile.
Narrowly beaten into second in a similar race at Newmarket in April, the 11-2 chance went one better in the hands of Oisin Muphy with a half-length verdict over Instant Attraction.
Williams said: "He was a little bit unlucky last time at Newmarket in a big handicap at the Guineas meeting. He'd have gone close that day if he'd got out a bit earlier.
"We made the plan to come here and it's all worked well.
"He's in the Hunt Cup and we might put him in the Wolferton as well. If he comes out of this OK we'll probably go to Ascot if we get in."
Jimmy Fortune produced Smuggler's Moon with a well-timed challenge to land the Investec Surrey Stakes.
The recent Newbury scorer was last of the eight-runner field with three furlongs to run, but started to make rapid ground soon after.
Scrutineer looked the likely winner after committing for home, but he was swamped late on, with 14-1 shot Smuggler's Moon getting up to beat Make Fast by three-quarters of a length.
The victory completed a double on Oaks day for Fortune, who had earlier steered Tullius to victory in the Diomed Stakes.
Imshivalla ran out a surprise winner of the second race on the card, the Investec Wealth & Investment Stakes.
A previous winner at the track, Richard Fahey's mare had finished well beaten on her last two starts and was a 25-1 shot for what was a fiercely competitive handicap.
Paul Hanagan's mount was never too off the speed and moved up to tackle the pacesetting Gold Prince with two furlongs to run.
Hot favourite Dark Red and the strong-travelling What About Carlo tried to make moves from further back, but they were unable to bridge the gap in the rain-softened ground.
Imshivalla eventually got the better of Gold Prince by a length and a quarter, with What About Carlo the same distance away in third.
Hanagan said: "I was a little bit worried as she was a bit keen behind them but I'm glad we went a nice gallop, she stuck on well.
"I've always thought a bit about her but she's highly-strung."
Fahey said: "She loves the course and it's nice to see her win.
"I was a bit surprised but she loves the ground and she loves the track.
"I don't know why she ran so poorly the last twice and there were no real excuses, she seemed fine.
"To be honest, she loves soft ground so wherever we get that, she'll go."
