Kieren Fallon (right, on Music Show) finished well to score by half a length
Kieren Fallon swooped late on the outside aboard Music Show (6-1) to win the Nell Gwyn Stakes at Newmarket.
The performance earned her quotes of between 7-1 and 10-1 for the 1,000 Guineas over the same course in May.
Music Show, trained by Mick Channon and the winner of the Rockfel Stakes aged two, was followed home by Blue Maiden (12-1) and Principal Role (13-2).
Henry Cecil's Oaks fancy Timepiece finished fourth in the Feilden Stakes, a race won by Rumoush (7-2).
Music Show, the daughter of Noverre, had all of her rivals in front of her passing the two-furlong marker but she made up plenty of ground thereafter.
And after quickening to the front, she stuck to her guns well to beat Blue Maiden by half a length in the seven-furlong race contested by 11 fillies.
Channon said: "You would have to be pleased with that as she has got very lazy this year and I wanted to get a run into her.
"I would have rather gone to Newbury but Jaber [Abdullah, owner] has got Lady Of The Desert running there so we had to come here.
"I have always thought she had a lot of class and Kieren didn't mess about - he knew what he had under him."
Blue Maiden's trainer Charlie McBride said: "I'm delighted. She just got held up in her run, a horse came in front of her and took her to the back of the field.
"Richard [Hughes, jockey] said that she'd be better with some give in the ground and bearing that in mind, we'll probably think about the Curragh and the Irish 1,000 Guineas."
Henry Cecil's Principal Role was far from disgraced in finishing third and Teddy Grimthorpe, racing manager for owner Prince Khalid Abdullah, said: "She has run really well and seven furlongs is probably a bit sharp for her. We'll probably step up to a mile and a quarter now."
Her stablemate Timepiece suffered plenty of misfortune in running during the nine-furlong Feilden Stakes. The 2-1 favourite finished fourth in a field of nine with Tom Queally looking for gaps that closed up on several occasions.
Marcus Tregoning's Rumoush maintained her unbeaten record, ridden with restraint by Richard Hills before being asked to take closer order at the three-furlong marker.
Hills coaxed his mount to the front before entering the final furlong, and at the first sign of a reminder from her jockey she stretched clear to score by two and a half lengths from Fighter Boy (40-1) with Marie De Medici (8-1) third.
Rumoush is generally a 10-1 shot for The Oaks based on her win on Wednesday, with Timepiece a similar price for the Epsom Classic and Principal Role 16-1.
