Former Kentucky Derby winner Animal Kingdom pressed the pace and then ran away down the stretch to capture Saturday's $10 million Dubai World Cup at Meydan Racecourse.
Trained by Graham Motion and ridden by Joel Rosario, Animal Kingdom was the 5-2 post-time favorite in United States' wagering among the 12 horses sent to the starting gate.
Longshot Red Cadeaux was second in the 1 1/4-mile race, with Planteur finishing third and Side Glance getting fourth.
Also in the field was champion female Royal Delta, the 3-1 co-second choice, and Dullahan, sent off at 5-1. Last year's winner, Monterosso, was scratched Saturday afternoon with an injured left front leg.
Royal Delta, ridden by Mike Smith, set the pace with Animal Kingdom, starting from an outside post, pressing the mare from her outside. Dullahan and jockey Gary Stevens were racing in the back of the field as the horses went up the backstretch.
With a half-mile to run, Royal Delta still had the lead as Animal Kingdom moved closer. The favorite gained the lead on the final turn and took charge with a quarter-mile remaining.
Animal Kingdom drove through the stretch as the 55-1 Red Cadeaux began a rally. However, the favorite was too strong and was able to post a 2 1/2- length victory.
The time for the 18th Dubai World Cup was 2:03.22 over Meydan's synthetic main track.
Owned by Team Valor, Animal Kingdom becomes the first United States-based thoroughbred to win the World Cup since Well Armed in 2009.
"We always knew he had a race like this in him," said Barry Irwin of Team Valor. "He showed us in the (Kentucky) Derby, we wanted to see it one more time. The Breeders' Cup was almost it, this was it.
"This horse never looked as fit before."
The 5-year-old earned $6 million with the win to bring his career bankroll to $8,387,500 with five wins in 11 starts.
Animal Kingdom first gained attention by winning the 2011 Kentucky Derby. His only other stakes win came in the 2011 Spiral Stakes, also on a synthetic track,
He began 2013 with a second-place finish behind Point of Entry in last month's Gulfstream Park Turf Handicap. The horse was second to Wise Dan in last year's Breeders' Cup Mile after being sidelined most of 2012.
Animal Kingdom may make one more start in England before being retired to stud in Australia,
In the United States, Animal Kingdom returned $7.40 and $3.00. Red Cadeaux paid $23.40 and Planteur paid $8.00. There is no wagering in Dubai.
