Brown Panther, bred and part-owned by former England striker Michael Owen, ran out an impressive winner of the Artemis Goodwood Cup.
Running over two miles for only the second time in his career, the five-year-old showed plenty of stamina and class to strike by three and a half lengths from Ahzeemah.
Richard Kingscote was trapped in behind horses on the 13-2 shot with two furlongs to run, but when the gap came Brown Panther shot clear and the race was over within a matter of strides.
The German raider Altano made late headway to claim third, but the 3-1 favourite Mount Athos was given plenty to do from the rear of the field and never looked like winning.
"As long as he didn't bomb out today we were thinking Irish St Leger" - Michael Owen
Michael Owen said afterwards: "There is a lot of heritage in this race and it's a fabulous race to win.
"He's full of stamina. We didn't want it to be a dawdle and hence we were up there in the box seat, just in case there was no pace.
"The leader all the way (No Heretic) did us a favour and gave us a nice lead. He's galloped all the way to the line.
"It's a great training performance from Tom Dascombe and a great ride by Richard Kingscote.
"With football you always feel you're in some sort of control. You and your team-mates are in control, but this racing game is so tough on the nerves - you're powerless.
"You send your jockey out to ride and you hope your trainer has got him spot-on. I was a little bit excited.
"We thought about the Melbourne Cup last year and we were thinking about it again this year, prior to this race.
"As long as he didn't bomb out today we were thinking Irish St Leger and then Melbourne Cup, so, on that performance, I don't see why we should change our mind."
Trainer Saeed bin Suroor said of runner-up Ahzeemah: "He ran a good race, he has a big engine and we were very pleased.
"We might go for a Group Three at Newbury next.
"I was disappointed with Colour Vision (seventh) - he didn't seem to handle the track."
