Godolphin's Saamidd made a most impressive racecourse debut at Newbury as he streaked seven lengths clear of the field.
Saamidd was sent off at 11-4 in what looked a decent gathering for division one of the Don Deadman Memorial EBF Maiden Stakes, but he showed a devastating turn of foot following a little squeeze from Frankie Dettori.
Totesport and Sky Bet were impressed enough to introduce the colt at 20-1 for next year's 2000 Guineas."He came here with a big reputation and he didn't let me down," said Dettori. "He gave me a good feel. I don't know what he beat but he did it in style."
Division two went to another choicely bred newcomer, the John Gosden-trained Treasury Devil (9-4).
The son of Crystal Music has been given some high-profile entries and will have done little to dissuade connections after William Buick surged to the front with a couple of furlongs to run.
The jockey and trainer combination then struck in the Punter Southall Transaction Services Handicap with the improving Kansai Spirit (5-1).
Ed McMahon's Electric Waves (10-1) collected the Listed Bathwick Tyres St Hugh's Stakes to follow on from the valuable success of stablemate Temple Meads in last month's Weatherbys Super Sprint over the same five furlongs.
On the same afternoon as the Super Sprint, this particular chestnut landed a nursery at Haydock.
Electric Waves and Richard Mullen put the event to bed at the furlong pole and she was good value for her length-and-a-quarter superiority over Sweet Cecily. McMahon said: "The ground has helped her. Coming on off a mark of 88, on paper, you'd think she'd have run well if she was third or fourth, but she's a filly that hasn't stopped improving.
The Ruthy Smith Memorial Maiden Fillies' Stakes saw 6-4 favourite Dark Promise nearly justify her skinny odds, but she was caught close to home by Jim Crowley and Red Intrigue (9-2).
Crowley added another aboard the veteran Foxhaven (11-8 favourite) in the Christopher Smith Associates Claiming Stakes.
Desert Poppy (2-1 favourite) took the step up to six furlongs well in the M C Seafoods Handicap, while Gross Prophet (8-1) won the Bettor Racing Tips At bettor.com Apprentice Handicap.
Connections of Field Day were delighted with the filly's fine performance in the Group Three Prix De Lieurey at Deauville on Wednesday.
Brian Meehan's three-year-old was tackling Pattern company for the first time in France and was beaten just a length by Via Medici.
Peter Reynolds, racing manager for the owners Ballymacoll Stud, said: "We were delighted with her and it was a great run.
"I think she'll probably get a bit further and I think she was a bit unlucky in the race as she met bad interference at the wrong time."
Marcus Tregoning has decided not to run Rumoush in the Darley Yorkshire Oaks at York next week and is eyeing an autumn campaign for the filly.
The Lambourn trainer wants to give the filly more time and is considering the Pride Stakes on Champions' Day at Newmarket in October as a possible long-term target.
"We'll hang on to her a bit longer. No particular plans for the moment, but she won't go to York," he said.
