Melbourne - Bubba Watson and Webb Simpson added the first point on the board for the Americans on a windswept day two at the Presidents Cup.
Watson and Simpson, the leadoff match for the second straight day, beat Ernie Els and Ryo Ishikawa again.
The American tandem never trailed and closed out the International side on the 17th hole for a 2-and-1 win in fourballs.
The Americans then went 6-2 up thanks to the pairing of Matt Kuchar and Steve Stricker who romped to a 4-and-3 win over Y.E. Yang and Robert Allenby.
Meanwhile, Tiger Woods made his first birdie of the Presidents Cup with one of the toughest putts on the course on the fourth hole.
However that was not enough as Woods and partner, Dustin Johnson narrowly went down by 1 hole to the all-Australian International pairing of Aaron Baddeley and Jason Day.
Woods almost chipped in from the back of the green for birdie and win the hole to halve the match, narrowly grazed the edge of the hole, giving Day and Baddeley two opportunities to halve the hole and win the match and score the first point of the day for the International team.
It would not last long as Phil Mickelson and Jim Furyk made it 7-3, defeating the International pair of Adam Scott and K.T Kim 2-and-1.
In the remaining two matches for the day the International side had the lead, including the pair of Charl Schwartzel and Retief Goosen, who were 2-up with three holes to play against Hunter Mahan and David Toms.
