Great Hall's win in the Dubai Duty Free Shergar Cup Challenge was a first Ascot triumph for trainer Mick Quinn.
Great Hall, a 12/1 shot, beat Gawdawpalin by a length and a quarter under Fran Berry.

Former footballer Quinn said: "He's been a little bit unlucky, this lad. Either the ground's dried out or there hasn't been enough pace, and the jockeys have come back and said, 'there's a nice one in him, there's a nice one in him.'
"I think it all fell into place today. We talked about tactics before. He wants a decent pace and to come from off the pace. Fran drove him up with a furlong to go and he held on. He had a nice pace, came there to win his race and he liked the ground as well.
"Fran's had three rides for me - two winners and a second. So it was three Hail Marys and two Our Fathers when the draw came out on Tuesday, and when the weights came out and I saw we were in it, I had a few quid on at 20/1.
"We're a small yard, 12 horses, and we don't have many runners here. I think the last was Angus Newz, an old sprinter we used to have.
"A nice prize like this gives you a great boost to keep going."
Berry, who is a previous winner of the Silver Saddle (2010) celebrated his third Shergar Cup success.
"I was delighted to get the call up, it's a privilege to be here, but even better to ride a winner," said Berry. "It's a big thrill, and even bigger for Mick Quinn, he's been good to me since I turned freelance.
"It's great to give Mick a top winner like this in a valuable handicap. It's big kick for him as he has a small stable. He had the horse in top shape and was quietly confident; the horse was back down to his best rating and the [soft] ground was a big factor for him."
