Hollie Doyle steered Bradsell to a decisive victory in the Coventry Stakes at Royal Ascot.
A relatively cheap breeze-up purchase at £47,000, Archie Watson's youngster made a big impression on his racecourse debut at York when winning by nine lengths with his head in his chest.
The son of Tasleet had significantly more on his plate stepping up to Group Two level, but proved more than up to the task under his record-breaking rider.
Always positioned wide from his low draw in stall two, 8-1 shot Bradsell moved smoothly towards the front end with two furlongs to go when Doyle made a bold bid for home.
It proved the right move as her mount soon found top gear to take a couple of lengths out of the field and from that point he never really looked in any danger of being reeled in.
The well-fancied Persian Force did best of the closing pack to fill the runner-up spot, but was a length and a half behind at the line.
Watson said: "I was probably a bit worried when it looked like the near side had won in front, he’s had to do it the hard way but he’s travelled into it supremely well.
"I said to Hollie to try to get a lead from those around you for as long as possible and that was as far as they took him into the race, he did hit the front two down and it’s a long way from home, but he kept going and he’s a supremely talented horse.
"It looked like a strong Coventry, I said to my fiance last night that what wins this in daylight will be a very good horse and it looks like he is.
"It’s massive, it’s our second Royal Ascot winner after Soldier’s Call. We had a bad old day here last year when Dragon Symbol was demoted and we subsequently lost the horse, it means a lot."
He added on plans: "He won’t be spammed into each and every race. He’s won the best Group Two, he’ll go to a Phoenix or a Morny I would imagine – if he was to run before it’d be something like a Papin."
Recording her third career win at the meeting, a delighted Doyle said: "I have done most of his work at home and the further he goes the better so I was not too worried when I committed, it was a long way from home (but) I knew he’d keep galloping.
"His instant response surprised me as in his gallops he is a little bit lazy, he turns it on on the track, he hit the line hard and I struggled to pull him up after.
"Off the back performance you’d have to say the world is his oyster.
"It is excellent for the team and great to be on board."
Andrew Balding's Coltrane (14-1) provided apprentice jockey Callum Hutchinson with his first taste of Royal Ascot success with a battling display in the Ascot Stakes.
A field of 19 runners went to post for the two-and-a-half-mile handicap, with Bring On The Night the favourite to provide Willie Mullins with a fifth victory in the race in the last decade.
A neck runner-up to Cleveland in last month's Chester Cup, Coltrane was guided to the lead inside the final two furlongs by his 5lb claimer, who punched the air as he saw off the challenge of Bring On The Night and Ryan Moore by three-quarters of a length.
Arcadian Sunrise made late gains to finish the same distance further back in third, with Going Gone fourth and last year’s winner Reshoun in fifth.
Saeed bin Suroor and Danny Tudhope combined to win the Wolferton Stakes with Dubai Future (20-1).
Fourth behind leading Prince of Wales’s Stakes contender Bay Bridge in the Brigadier Gerard Stakes at Sandown last month, the six-year-old looked far more comfortable stepping down to Listed class.
He loomed up travelling strongly early in the home straight before kicking clear, with favourite Cadillac – who changed hands for £500,000 at the Goffs London sale on Monday evening – beaten three lengths into second place.
Tudhope completed a quickfire double in the concluding Copper Horse Stakes aboard the David O’Meara-trained Get Shirty (16-1).
Already successful at Thirsk and Hamilton this season, the six-year-old burst through against the far rail to beat favourite Cleveland by a length and a quarter.
