Gleneagles - Hunter Mahan has fired five birdies and an eagle as he and Jim Furyk defeated Europe's Lee Westwood and Jamie Donaldson 4 and 3 in Saturday's second Ryder Cup fourballs match.
Mahan birdied to win the opening hole at Gleneagles, Furyk birdied to capture the third and when Mahan birdied the seventh, the US duo led 3-up.
After halving the next six holes, three with birdies and three with pars, the Americans moved 4-up on Mahan's eagle at 14 and closed out the match on Mahan's three-foot par putt to halve the 15th.
Furyk broke his own Cup record with a 16th different partner in Mahan and took his first-ever pairs victory over Westwood, a fellow nine-time Cup starter who had been 5-0 with two halved against Furyk.
