The hosts produced the most dominant singles day in the history of the competition to win nine of the 12 singles matches and chalk up their 11th victory in a row over the International team.
"Is it a record in singles? That doesn't happen unless you have a special group of guys, and we do," said USA captain Brandt Snedeker afterwards.
"I'm really proud of how they came together. I told the guys last night that funny stuff happens here. Medinah has a history of funny things happening. Sure enough, they went out and played their [tails] off today. I'm so damn proud of those guys."
It was obviously not without drama. A gallery member yelled during Nico Echavarria's backswing in his match against Scottie Scheffler, causing him to drop the driver as his ball sailed right. Scheffler immediately called out the fan. Then after missing a birdie putt, Scheffler conceded a 30-foot par to Echavarria in a great show of sportsmanship. The world number one would go on to win 2&1.
Another storyline worth mentioning came from 21-year-old Jackson Koivun. Two behind Si Woo Kim through 10 holes, Koivun rallied to win three consecutive holes and flip the color to American red on the board. Koivun was solid on the last to claim a 2-up victory.
"The kid is special, he's different," continued Snedeker.
"You saw that for a 21-year-old kid to stand up there and hit those last two balls like he did. Not many people like that."
At the other end of the spectrum, International captain Geoff Ogilvy admitted it was always going to be difficult on Sunday. But at three up heading into the final day, he had dared to dream.
"Look, it's a very difficult thing to beat the US in singles in the US," Ogilvy said.
"They're great players, and the crowd came out for them. They get a bit of red on the board, and the noise gets loud. They started the day with a lot to do and they all played great."
