"The horse has been training unbelievably well and every week has been firing bullets at Keeneland, but I'll tell you what, Frankie is superb. You can have a Porsche against Porsches, but you still gotta have the right guy (at the wheel) and this is a magical guy. He's just a cool sitter and a go-getter as they say," Ward commended the champion rider. "It would have been so easy to lay up with this horse, but Frankie just sat back there, got him wide and came home with the rest. It was fantastic."

"Wesley is a very, very good friend of mine and a big supporter of mine. Nothing gave me more pleasure than winning this race for him," Dettori said.

"(Undrafted) jumped out of the gates like an American horse but I took a pull as I didn't want to get there too early. I was trying to save a bit for the end. I kept an eye on the Australian horse and we kicked on, I knew it would take a good one to get by him. When you sit on a sprinter like that you get a great feeling.

"I didn't want to kick too soon because I was going so well. I kept an eye on the yellow colors but, every time this horse runs, he finishes strong so I saved the last bit for the end and it proved me right. I knew that I had won."

Undrafted, a 14-1 shot who scored by a half-length over the Australian runner and 7-2 joint-favorite Brazen Beau (I Am Invincible), became Ward's fifth Royal Ascot winner but his first by a horse older than two. Undrafted carried the colors of NFL star Wes Welker, who was unable to travel to Britain and was represented by his racing manager, Gatewood Bell.

"Gatewood Bell, a wonderful bloodstock agent, picked the horse out as a yearling and I broke him in," Ward remarked. "Wes has been a dream owner and a fantastic guy to train for -- it was like I owned the horse because I could do anything with him from the time he came to me. One of the reasons for the success is that if I want to give the horse a winter off like I did last year he's happy for that. It's a shame he's not here today."

Undrafted entered the Diamond Jubilee off a pair of placings to start the year in Kentucky. The chestnut gelding was third in the Shakertown S. (G3) at Keeneland on April 4 before just missing when second by three parts of a length in the Twin Spires Turf Sprint S. (G3) at Churchill Downs on Kentucky Oaks Day, May1. Prior to Saturday, his biggest score had come as a win in last year's Jaipur Invitational (G3) at Belmont Park and he also posted a half-length third in the Breeders' Cup Turf Sprint (G1) to close out his 2014 campaign.

"He's a tremendous horse at the top of his game," Ward said. "I've been on the phone to Frankie for weeks and weeks, telling him how good the horse is. I felt that given the right ride over the right trip we could get the job done and we did.

"We're going to sit down and talk about the July Cup (at Newmarket), but no decision has been made."

Undrafted is now 6-1 from 14-1 for the July 11 July Cup (Eng-G1), a race he ran fourth in last year, with Betfred and Paddy Power. Brazen Beau is Paddy Power's 4-1 favorite.
