The United States will take a one-point lead into Sunday's singles against the Internationals at the Presidents Cup.

USA led 5½-4½ going into the third day at Jack Nicklaus club in Incheon, South Korea and are now 9½-8½ up.

Jordan Spieth and Dustin Johnson pulled off one of the comebacks of the event to beat Internationals pairing Jason Day and Charl Schwartzel.

The USA duo trailed by three holes at one point but Spieth drained a seven footer on 18 to win the match.

Meanwhile, it has been announced that Melbourne will host the 2019 edition of the Presidents Cup and the 2016 World Cup of Golf.

Spieth & Johnson stun Day & Schwartzel

The USA had lost one and halved two matches in the morning before Spieth and Johnson turned their match around to share the foursomes 2-2.

They were three down at the turn and one down with two to play before Spieth holed a couple of seven footers to win the match for the defending champions.

"That was a great fight. And it was a huge point in the Presidents Cup," this year's Masters and US Open winner said.

In the other matches, South Africans Louis Oosthuizen and Branden Grace earned their third straight win by beating Patrick Reed and Rickie Fowler 3&2.

Bubba Watson, who was paired with J.B. Holmes, missed a five-foot putt on 18 which would have secured a win over Australians Adam Scott and Marc Leishman instead of the match being halved.

Home favourite Bae Sang-moon and Japanese partner Hideki Matsuyama also fought back on the last to earn a half point against Bill Haas and Matt Kuchar.

Spieth shines again

World number one Spieth then teamed up with Reed to defeat Day and Schwartzel for a second time in the concluding fourball contest and ensure the Americans would lead going into the final day.

Spieth turned the match around with a run of three straight birdies from the seventh to go two up, before a birdie from Reed on the 11th and Spieth again on the 12th put them all but out of sight as darkness fell.

"I would call it unplayable," said Spieth, who carded eight birdies in the 16 holes played. "If it was a tied match, we would not have played the 16th hole. It was too dark."

The teams took two wins each in the fourballs, with South African pair Oosthuizen and Grace beating Holmes and Watson, Phil Mickelson and Zach Johnson defeating Australia's Adam Scott and India's Anirban Lahiri 3&2, and Bae and Matsuyama thrashing Jimmy Walker and Chris Kirk 6&5.

In the draw for the singles, Spieth will face Leishman in match eight and Day to face Johnson in the following pairing.
