High Chaparral, who was supplemented to the field, overtook The Tin Man who had led into deep stretch and finished 1 1/2-mile turf course in 2:30.14.
"He really stayed well," winning jockey Michael Kinane said. "They really didn't go that quick." But, he said, when he asked the 3-year-old son of Saddler's Wells to move, "he went to the front very easy."
High Chaparral, owned by Michael Tabor and trained by Aidan O'Brien, sat behind the leaders for most of the trip, making his move in the final furlong between horses.
High Chaparral finished 1 ¼ lengths ahead of late-running 7-year-old With Anticipation. Falcon Flight was another ¾-length back with a rush in the stretch. The Tin Man finished fourth.
High Chaparral paid $3.80, $3 and $2.60; With Anticipation, $5.20 and $4.20, and Falcon Flight, $5.20. The $2 exacta returned $34.80.
High Chaparral finished third in the Arc de Triomphe at Longchamp in his last outing -- a race in which O'Brien said he was "a bit rusty." He previously chalked up six straight wins. The victory in the Turf provided a bright spot for O'Brien, whose Landseer suffered a fatal breakdown and whose Rock of Gibraltar got off to a bad start in the Mile, finishing second.
"This made up for the day," Kinane said.
This year's Turf drew the smallest field in the championship series' history -- just eight horses in what has traditionally been a showcase for European horses, who had won the race nine times in the 18 previous runnings.
The winners $1.4 million share of the purse pushed High Chapparal's lifetime earnings past $3.7 million.
