Rory McIlroy and Tommy Fleetwood maintained their perfect Ryder Cup record together as Team Europe built a record-equalling 8.5-3.5 lead after the Saturday foursomes in New York.
McIlroy and Fleetwood won both foursomes matches together during Europe's 2023 success in Rome and repeated the feat on away soil, beating Collin Morikawa and Harris English for a second successive day.
They withstood a brief fightback from the American pair and hostile home crowd to win 3&2 and earn one of three points for Luke Donald's side in another impressive session, with their five-point advantage leaving them just 5.5 points away from retaining the trophy and six for outright victory.
Jon Rahm joined Fleetwood in registering a third win of the week, partnering LIV Golf team-mate Tyrrell Hatton to 3&2 win over Xander Schauffele and Patrick Cantlay, while Bob MacIntyre and Viktor Hovland held off world No 1 Scottie Scheffler and Russell Henley to claim a 1up victory.
Team USA's only point came in the top match, where Bryson DeChambeau and Cameron Young secured a 4&2 win over Ludvig Ã…berg and Matt Fitzpatrick, with Keegan Bradley's side now requiring a historic comeback to avoid a home defeat.
A fast start from Team USA saw Young almost hole his approach into the first and left Ã…berg having to hole his putt to halve the hole with birdies, with the New York native the chipping in from the fringe to win the third.
Europe claimed the next but saw the hosts take control when DeChambeau and Young claimed three holes in four from the seventh, with Fitzpatrick holing a 15-foot birdie at the 12th to avoid falling further behind.
A conceded birdie at the 16th closed out a first Ryder Cup foursomes point for DeChambeau, but Europe quickly extended their advantage when McIlroy and Fleetwood continued their unbeaten starts to this year's contest.
The pair responded to losing the opening hole to grab a two-hole advantage after birdieing their next four holes, with pars then enough to win the seventh and eighth and reach the turn four clear.
Fleetwood missed a par putt at the 14th and English birdied the next to briefly threaten a comeback, only for McIlroy - having offered an expletive-laden reply to a heckle in the crowd - to fire a stunning approach into the 15th and close a match-winning birdie.
Rahm and Hatton won the first two holes of match three and shared the next two with birdies, before bouncing back from losing the fifth and seventh holes by claiming the eighth when the Spaniard produced a sensational chip in.
Hatton birdied the 12th before the pair wrapped up victory with two holes to spare, with American hopes dashed further when Scheffler became the first world No 1 in history to lose the first three sessions in a Ryder Cup.
Hovland and MacIntyre won two of the first five holes but saw their lead disappear when Scheffler birdied the 11th and Henley made one at the par-five 13th, before edging back ahead with a birdie-two at the 14th.
Both captains watched on as Hovland holed a clutch par-save at the 17th to maintain Europe's lead in the match heading to the last, where a par was enough for another point - matching Europe's three-session advantage when they won their first away Ryder Cup in 1987.
"Russ [Henley] and I battled hard out there," Scheffler said. "The guys we played against just played great. They did a good job. They holed the key putts. Obviously disappointed with the finish, but battled pretty hard this morning.
Europe are just the fourth side in Ryder Cup history to win each of the first three sessions, with all the previous three going on to win, leaving Donald's side firm favourites to register a first away victory - from either team - since the 2012 'Miracle at Medinah'.
"It [performance of star players] is massive," Donald explained. "Two years ago, our superstars, Rory [McIlroy], Viktor [Hovland] Jon [Rahm], all made a lot of points and they are playing together.
"You need your superstars to perform at their highest and they certainly have showed that so far. Every point matters. A half-point is great, but we've got a lot more points to go, but valuable points."
