INCHEON, South Korea — Phil Mickelson and Zach Johnson won the only match that reached the 18th hole Thursday, the final touch on another dominant day for the Americans in the Presidents Cup.
The rest of the foursomes matches were not much of a contest as the Americans built a 4-1 lead after the opening session.
It was the fifth straight time the Americans have taken the lead in the opening round of this one-sided contest, and the three-point lead was their largest margin since they had a four-point lead in 2007 in Canada.
The Americans are going for their sixth straight victory, and after one day at the Jack Nicklaus Golf Club Korea, there was a familiar feel to the event.
