The United States owned a five-point lead at the start of the day, but saw that advantage cut to 7-5, with 22 more matches scheduled over the weekend.
Singh and Appleby recorded a 5&4 win over Woods and Furyk, as the International Team won four of the six fourball matches and halved another.
The match featured Austin trying to make an impossible shot from a pond alongside the green at the 14th hole. The ball was submerged, and in trying to make the shot Austin lost his balance and tumbled into the water.
Austin came back to birdie the final three holes.
Steve Stricker and Scott Verplank had the lone American win, a 2&1 decision over Adam Scott and K.J. Choi. Retief Goosen and Angel Cabrera won the final hole to defeat Phil Mickelson and Hunter Mahan, 1-up.
