The U.S. began the day with a commanding 8-2 lead, their biggest ever after two days of Presidents Cup competition, and stretched it to an nearly insurmountable 11 1/2 - 2 1/2 advantage after the morning matches.
A ruthless United States showed a shattered global team no mercy winning three of the four foursomes matches on Saturday to sit on the brink of a seventh straight Presidents Cup title.
The task won't be easy, though, as Spieth has never lost a foursomes match in the Presidents Cup (4-0-0).
The United States surged into an 8-2 lead after Friday's four-ball matches at the Liberty National Golf Club.
World Number 1 Johnson caught fire on the back 9 and wrapped up the match for the US on the 16th winning 3 & 2.
Recently-crowned FedEx Cup victor Justin Thomas and Rickie Fowler overcame South African pair Louis Oosthuizen and Branden Grace 3 and 2, but with the three remaining contests close at that stage the worldwide side would have harboured hopes of reducing the deficit. Spieth and Reed were forced to forfeit the hole as a result, and Oosthuizen and Day took a 1-up lead even though they lobbied with the rules official that Spieth and Reed not be penalized. Two years ago in South Korea after tumbling into a similar Day 1 hole, the global side rallied by winning four of the fourball matches.
Grace will play with Leishman against Johnson and US Open champion Brooks Koepka in the anchor match. The International team can be backed at 25/1 for a remarkable win and the tie at 15-15 is available at 20/1.

Matsuyama said that Hadwin had carried him on the back nine, as the worldwide duo surrendered a two-up lead over the final four holes. Barring something insane, expect the afternoon four-ball to send Chappell and Hoffman out first, with the morning pairings somewhere behind. "They came into this event riding a lot of momentum, a lot of confidence, and they really get excited to play these team events and it's showing".
The International's standout pairing comes in the last match of the morning, as Grace and Oosthuizen tee off together.
"We'll see how it goes", said Price, whose team just hasn't had the firepower to rebound against a US team that has combined for 17 US PGA Tour titles this season, including the three most recent major championships. Still 2-up with just four to play, it looked as though the Americans would drop the opening match in heartbreaking fashion.
Their story encapsulated the troubles for the Internationals; starting with three consecutive birdies they had control of the match, then gradually surrendered it.
Absolutely, we say, and as global captain Nick Price pointed out, only 10 of the possible 30 points have been accounted for after the initial foursomes and four-ball sessions. But the Aussies fought back, taking a 1-up lead at the seventh hole with a chip-in birdie from Day.
In amongst that he virtually left Schwartzel one-out against the Americans with a string of bad shots.
Oosthuizen will team with Day against Spieth and Reed in the first afternoon match. Vegas birdied the next hole from 35 feet, and that's when Johnson took over.
