William MUIR hailed Restorer "the real deal" after the newcomer made an impressive start to his career and completed a Ffos Las double for the Lambourn trainer.
The Mastercraftsman colt was an 8-1 shot for the PT Civil Engineering Maiden Stakes, with fellow debutant Bold the 11-10 favourite for Roger Charlton.
After a slow start, Bold moved threateningly into the contest, but Restorer showed smart acceleration in the rain-softened ground and was three lengths too strong in the hands of Martin Dwyer.
Muir said: "Martin rode him work on Friday of last week and got off him and said, 'You've got a proper one here'.
"I told him I was going to run him over a mile at Ffos Las and he told me I was crazy as he had so many gears he should be running over six furlongs.
"I knew he was bred to get the mile and he's obviously just a very good horse," he added.
"Martin said he was the first two-year-old who has really carried him into the race for a long time. He's real deal and really could be anything.
"We haven't got any plans for him at this stage. We'll just wait and see what the handicapper does and go from there."
Thirty minutes earlier, Muir and Dwyer initiated their brace with Improvized in the Walters UK Handicap.
Also an 8-1 shot, the three-year-old filly was slowly away but came home well to take the prize by two lengths from 50-1 outsider Sarlat.
"To be honest, we've been getting her wrong all year," said Muir. "She won first time out over seven furlongs last year and was still very week and we thought she would want stepping up in trip this season.
"She's been running from a mile and a quarter to a mile and a half and just hasn't been getting home, so she's come back to a mile today and Martin said that's her trip. He said we shouldn't sell her on the cheap as she's still a weak filly and she could easily go and win two or three more for us, so we'll see where we go from here."
The Muir-Dwyer combination looked likely to complete a hat-trick in the Walters Land Rogerstone Handicap, but the strong-travelling Big Baz eventually gave way to Andrew Balding's 20-1 shot Merry Me.
Noel Quinlan's Newcastle maiden winner Park Glen (11-4) made a successful start to her handicap career with a good effort in the Walters Land Rogerstone Nursery under excellent apprentice Sam James.
The Michael Blanshard-trained Fair Comment was a 6-1 winner of the Arup Fillies' Handicap in the hands of David Probert, while Reach The Beach (7-2) ran away with the Neal Soil Suppliers Handicap for trainer Brendan Powell and jockey Adam Kirby. Kirby signed off with a double as he steered Clive Cox's 4-1 shot Le Maitre Chat to success in the concluding Walters UK Maiden Stakes.
