The United States' bid to win an 11th consecutive Presidents Cup was dealt a huge blow after the International team came roaring back on day two.
Brandt Snedeker's red, white and blue held a narrow 3-2 lead after day one but trail by four points after Geoff Ogilvy's side won all five foursomes matches on Friday at Medinah Country Club.
They were led by an inspired performance from Canadian duo Nick Taylor and Corey Conners in the opening match, who took down world number one Scottie Scheffler and Sam Burns on the final hole.
Sungjae Im and Hideki Matsuyama then completed a comfortable 3&2 victory over Jacob Bridgeman and Russell Henley.
Elsewhere, reigning Open champion Ryan Fox and Min Woo Lee were involved in a tense match against Collin Morikawa and Wyndham Clark that went down to the wire.
But the champion golfer of the year held his nerve on the 18th by holing a nervy five-footer to complete a 1up win.
Justin Thomas and Cameron Young were unable to make a single birdie and were comfortably defeated by Adam Scott and Christiaan Bezuidenhout.
South Koreans Tom Kim and Si Woo Kim then put the cherry on the cake with an incredible 4&3 win over Patrick Cantlay and Xander Schauffele.
It means Ogilvy's side lead the 16th edition of the Presidents Cup 7-3.
