Mohaather demonstrated a devastating turn of foot to win a stellar renewal of the Qatar Sussex Stakes at Goodwood.
Trained by Marcus Tregoning and ridden by Jim Crowley, the four-year-old endured a luckless run in the Queen Anne Stakes at Royal Ascot – but righted the record as an impressive victor in a top-class running of the Group One showpiece.
Queen Anne winner Circus Maximus set out to make all under Ryan Moore and the field was closely bunched with two furlongs to run as the leader tried to press on, with San Donato the first to make his bid and briefly looking as though he could be set to produce a shock.
However, the previously-unbeaten Siskin then unleashed his challenge down the outside, with Crowley producing his mount even wider still and once he did Mohaather (3/1) fairly flew in the final furlong to collar Circus Maximus and score a first top-level victory.
Irish 2,000 Guineas hero Siskin dropped back to third, with Kameko – winner of the Newmarket Guineas – fourth having been tight for room in the closing stages.
Marcus Tregoning said: "I have had to wait a long time for this, but quite honestly we didn't have the horses. When I left Lambourn I had to start again with not very many - it was like starting from the beginning. Luckily, Sheikh Hamdan supported me very well.
"It's a big day for the team and for Sheikh Hamdan. He is a very good owner to train for. He is a lot of fun and a lot of people don't see that. He takes adversity really well; when things don't go right, move on. To have someone with so much confidence behind you does make you a better trainer.
"It was a tactical race today and we thought it would be. He struggled to get out, he is not the biggest horse and he struggled to find a gap, but Jim [Crowley, jockey] kept his calm and with the knowledge that he has that massive kick.
"It was a little bit of a nightmare to watch, but I knew if Mohaather got out, he would have the speed; he has got a very good turn of foot, as you can see. I know it's a well-used expression, but he does find heaps under pressure, and I couldn't have been happier with the way he came into the race - the team have done a great job. Obviously, I am lucky to train horses for Sheikh Hamdan, because he has been an avid supporter, so we are all thrilled.
