Elhamri overcame an unfavourable draw and a penalty picked up at Royal Ascot to notch a front-running victory in the Weatherbys Super Sprint at Newbury.
The son of Noverre may be small but he lacks nothing in heart and thundered home on the rain-softened ground to beat 100-1 outsider Ishi Adiva by a length.
Sylvester Kirk's charge broke from stall 12 in the five-furlong dash and he had it all to do with only a handful of previous winners having defied a middle draw in the £135,000 contest.
To make matters worse, the juvenile was lumbered with an extra 8lb after his win in the Windsor Castle Stakes, which also came under Declan McDonogh.
The jockey - having his first ride at Newbury - kept a cool head and after breaking well, the pair bowled along in front before finding more close home for a cosy victory.
Ishi Adiva, who only had two runs in maidens to her name, ran out of her skin for trainer Tom Dascombe when taking second while 20-1 shot We'll Confer was third.
Kirk said: "He is a tough horse but I thought they were going to come and do him with the penalty. It was a nice performance with that weight.
"I told Declan to go straight up the middle and see what happens and he said he thought he always had some-thing left.
"He found another gear in the final half furlong, just when I thought they would get to him."
The winner disappointed on soft ground at Goodwood earlier in the campaign and Kirk had contemplated taking him out after a lunchtime downpour.
"I sat depressed in the car for half-an-hour as I thought his chance had gone with the rain," Kirk continued.
"Up until the after the first race I was considering taking him out as he ran so bad on soft ground at Goodwood but he is a two-year-old and there are not that many opportunities."
The Molecomb Stakes at Glorious Goodwood might now come into the equation for the winner with Kirk also considering a trip to France for the Prix Morny.
McDonogh has partnered Elhamri on all four of his starts and he said: "He is tough and has a great attitude. It was the same when he won at Windsor.
"It took him half a furlong to find his action on the ground and he was rolling around on it towards the start.
"He is only a handy horse but he is well made and he loves it when things get tough."
Richard Hannon sent out a trio of runners in pursuit of his seventh win in the race but it was not to be, although his tough-as-teak filly Gilded fared the best when taking sixth having been sent off the 11-4 favourite. Her jockey Richard Hughes said: "She got her head under the stalls and lost a few lengths at the start." n Graham Gibbons and Gyles Parkin were prevented from riding on Saturday after failing breathalyser tests at Ripon.
T he sampling officer reported to the stewards that both jockeys provided breath samples that were found to contain alcohol in a concentration above the permitted threshold level.
The stewards suspended Gibbons and Parkin from riding for the day and the matter has been referred to the Horseracing Regulatory Authority.
Gibbons had two booked mounts at Ripon and two at Haydock's evening meeting while Parkin had to give up one ride at each.
