Six of Lake Nona's 10 players shot in the 60s, including captain Ernie Els, who fired a 69.
ORLANDO, Fla. (AP) -- Graeme McDowell shot a 6-under 66 and the rest of his team at Lake Nona piled on Tuesday to win the Tavistock Cup 17-13 against an Isleworth team led by Tiger Woods.
"It's about time we won this thing again," Lake Nona captain Ernie Els said.
McDowell won the Payne Stewart Silver Award for having the lowest score in final round of singles medal matches.
The Tavistock Cup, held this year at Lake Nona, is a competition between two high-profile golf clubs in Orlando where several prominent PGA Tour players are members.
The final round featured two-man teams in stroke play matching scores against each of the two players from the other club. Woods and Charles Howell III each had a 69 and picked up three points in the final match. They halved with Ian Poulter and beat Henrik Stenson. But the cup had already been decided.
Ben Curtis (68) and Trevor Immelman (69) gave Lake Nona four points in the first match over Mark O'Meara and John Cook, and Lake Nona quickly pulled away. Six of its 10 players shot in the 60s, including Els (69) and Justin Rose (68).
Darren Clarke (68) had the low score for Isleworth.
