Dublin, OH (SportsNetwork.com) - The United States extended their lead to six points as the foursomes action that was suspended on Saturday wrapped up on Sunday morning at The Presidents Cup.

The U.S. leads the Internationals, 14-8. Sunday's singles matches got underway earlier than originally scheduled as there is more inclement weather in the forecast for Sunday.

Zach Johnson's hole out eagle earned him and Jason Dufner a 4 & 3 win over Marc Leishman and Richard Sterne on Saturday. That was the lone match to end before darkness halted play.

When the teams returned to Muirfield Village in the morning, Keegan Bradley and Phil Mickelson fought to a halve with the International duo of Jason Day and Graham DeLaet. DeLaet chipped in for birdie on the 18th before Bradley rolled in a 10-footer for birdie and the halve.

Americans Bill Haas and Steve Stricker closed out Adam Scott and Hideki Matsuyama, 4 & 3.

The final two matches ended in 1-up decisions, with one going to each team. Webb Simpson and Brandt Snedeker won four of five holes from the 13th to rally from a 3-down deficit to earn a 1-up win over Louis Oosthuizen and Charl Schwartzel.

Ernie Els converted a 4-foot par putt to give him and Brendon de Jonge a 1-up win over Tiger Woods and Matt Kuchar, who lost for the first time this week. The Internationals led the whole match, and were 3-up with four to go before the Americans won 15 and 16 to cut the deficit to 1-down, but the teams halved the final two holes.
