William Buick has continued his fairytale first season as stable jockey to John Gosden by steering Arctic Cosmos to victory in the English St Leger.

The Norwegian-born Buick added the world's oldest classic to a collection of big race wins for the Newmarket stable this year that have included the Arlington Million and Dubai Sheema Classic.

Arctic Cosmos was sent off a 12-1 shot behind even money favourite Rewilding representing the Godolphin team and ridden by St Leger specialist Frankie Dettori.

Corsica, trained by Mark Johnston, belied his 40-1 odds by setting a searching pace and dominating affairs right up to the closing stages of the one mile six furlong (2800m) Group One.

In the final furlong Dettori switched Rewilding towards the rails for his run but it was Aidan O'Brien's Midas Touch who looked the danger coming down the centre of the track.

But Arctic Cosmos held the upper hand, displaying bags of stamina. He had already hit the front and he kept galloping to the line to hold off Midas Touch (13-2) by a length and three quarters.

Corsica, who was supposed to have been performing pacemaking duties for Rewilding, held on for third ahead of Rewilding, who failed to justify a major gamble.

Arctic Cosmos wore blinkers for the first time and 22-year-old Buick said the had helped.

"He's been dossing all year, he's still a big baby, we put blinkers on to sharpen him up," Buick said.

"This is unbelievable, winning the St Leger is very special."

While it was a first St Leger for Buick, Gosden celebrated his third success in the Doncaster classic.

"We might just give him his next race in the Breeders' Cup Turf in November," he said.

"He'd worked well at home, a little lazy, I expected him to be in the three, but couldn't see him beating the favourite who obviously didn't run his race.

"He's gone and done it well, we'd always dreamed of him being a St Leger horse when we bought him but it often doesn't work out that way."
