After the second day of play in the Presidents Cup, former world number one Tiger Woods is the only American yet to make a contribution towards his team's bid for a fourth successive win.
What is more, this is the first time he has lost his first two games in a matchplay format since the 2004 Ryder Cup in Detroit.
Greg Norman's International team were 4-2 down after the first-day foursomes, as both sides struggled with windy conditions on day two.
The International pairing of Geoff Ogilvy and KJ Choi beat Bill Haas and Nick Watney on the 18th hole, while Americans Matt Kuchar and Steve Stricker eased to a 4&3 victory over Robert Allenby and YE Yang.
Mickelson and Jim Furyk beat Adam Scott and KT Kim 2&1, while Bubba Watson and Webb Simpson beat Ernie Els and Ryo Ishikawa 3&1, the second consecutive win for both US duos this week.
South Africans Retief Goosen and Charl Schwartzel ensured the day ended 3-3 when they finished off David Toms and Hunter Mahan 2&1 in the final match of the day.
On Day three, Woods will face Scott again, when he pairs up with Johnson to face Scott and Choi.
