Drosselmeyer thundered through the finishing stretch to win the $US5 million Classic on Saturday, capping the two-day, $US26 million Breeders' Cup meeting under the floodlights at Churchill Downs.

As the two-time Cox Plate winner So You Think finished unplaced, jockey Mike Smith claimed a record-equalling 15th Breeders' Cup win on the horse trained by Bill Mott.

Mott completed an impressive Breeders' Cup double after saddling Ladies' Classic winner Royal Delta on Friday.

"He was mowing them down the last eighth of a mile," Mott said.

"I guess his biggest attribute is his stamina, and he showed it today. When they were wearing down, he was coming. It's great."

Drosselmeyer won for just the second time since his triumph in the 2010 Belmont Stakes.

Drosselmeyer had fallen back to next to last but roared home to overtake Game On Dude - ridden by Smith's former fiance Chantal Sutherland.

"He really dug in," Sutherland said of Game On Dude. "He ran every inch of the way and he was really tired at the end. I've never seen him that tired. I am so proud of him."

Ruler on Ice - an upset winner in this year's Belmont Stakes - was third.

Smith's victory came a year after his emotional near-miss in the Classic aboard beloved Zenyatta, a defeat that left the great mare's "devastated" rider in tears.

"Last year hurt and still hurts and will for the rest of my life, but this is great," said Smith, whose Breeders' Cup tally matches Jerry Bailey's record total for a jockey.

Smith had claimed his 14th win earlier in the day aboard Amazombie in the Sprint.

So You Think, the New Zealand-bred who has starred in Australia and Europe, challenged under Ryan Moore, keeping the leaders in view despite his unfamiliarity with the dirt.

In the end, however, he couldn't come up with a finishing gear.

"He ran a great race. He handled the track well, but speed is a big thing, and we would have liked them to have gone a little faster," trainer Aidan O'Brien said.

Moore said: "He just ran out of petrol toward the end. It was his first run on the dirt, in the toughest race in North America.

"He ran a very creditable race. It was worth a chance to find out."

Uncle Mo, who had been made the early favourite on Monday, finished a disappointing 10th.

A stellar two-year-old in 2010, Uncle Mo was trying to complete his comeback from a liver ailment that kept him out of the Kentucky Derby in May.

"I thought we were in good position, but he didn't settle really well," said trainer Todd Pletcher.

Uncle Mo's jockey John Velazquez said: "He was struggling with the track for whatever reason.

"I tried to give him his head where he would feel comfortable, but he never really got into a good rhythm to get a good grip of the track.

"I didn't want to beat him up in the stretch when everybody started going by me."
