Team Europe secured an opening-day lead in an away Ryder Cup for the first time since 2004 after building an impressive 5.5-2.5 advantage over Team USA at Bethpage Black.
, Europe's largest opening-session advantage on away soil in 21 years, then added 2.5 points - in front of an increasingly raucous New York crowd - later in the day.
Jon Rahm claimed his second win of the event by partnering Sepp Straka to a 3&2 success over JJ Spaun and world No 1 Scottie Scheffler, who was beaten in both of Friday's sessions.

Cam Young made the dream start to his Ryder Cup debut when he teamed up with Justin Thomas to thrash Ludvig Ã…berg and debutant Rasmus Hojgaard 6&5 and claim the Americans' only win of the afternoon fourballs, while the other two matches delivered closer finishes.
Justin Rose delivered a final-hole birdie to secure him and Tommy Fleetwood a 1up win over Bryson DeChambeau, who was walked to the tee by President Donald Trump, and Ben Griffin, before Rory McIlroy and Shane Lowry finish tied with Patrick Cantlay and Sam Burns in a thrilling final match.
"Obviously right now, disappointed I didn't hole out for a full point," McIlroy said. "But it's been a great day for Europe. We have come out of the gates really strong like we wanted to. We should be really proud of ourselves."
The last five teams to be leading the Ryder Cup after the opening day have gone on to win the trophy, with Donald's team off a dream start to their bid for a historic title defence on American soil.
Spaun opened his Ryder Cup debut with a close-range birdie alongside an out-of-sorts Scheffler but quickly fell behind against the European pair, who won the next two holes before Rahm extended their lead with birdies at the eighth and 11th.
Straka holed from 30 feet to match Spaun's birdie at the 14th and Rahm converted from long-range to join Scheffler in birdieing the next, with Europe getting their first point of the session when Straka rolled in a birdie at the 16th.
It restored the two-point cushion for Team Europe, having seen Young and Thomas register the biggest American fourballs victory this century. The American pair claimed four holes in a five-hole stretch to wrap up victory with five holes to spare.
DeChambeau almost drove the opening green - in front of President Trump - and edged his pairing ahead with a birdie at the fifth, while Rose had to hole from 40 feet at the seventh to match the sensational birdie from Griffin and avoid falling further behind.
Fleetwood responded by following birdies at the 11th and 14th with another at the 16th, putting the European pair two ahead with two to play, only for DeChambeau to birdie the next and take the contest to the par-four last.
Rose responded by firing his approach to 10 feet and slotted in the winning birdie, extending Fleetwood's 100 per cent start and moving Europe 5-2 up, before the final match also went to a final-hole decider.
A topsy-turvy contest saw McIlroy and Lowry recover from losing the opening hole to build a two-shot lead with seven holes to play, only for Cantlay to birdie the 12th and pull level when McIlroy lipped out from five feet at the next.
Cantlay squandered his own close-range chance at the next but birdie the 16th to put pressure on McIlroy, who converted from 10 feet and then matched Burns' birdie at the par-three next.
Both European players found the green in regulation and McIlroy had a putt for victory when Griffin missed his birdie try, but the world No 2 was unable to convert his effort and missed out on extending Europe's commanding cushion.
Team Europe captain Luke Donald:
"Incredible day. To win this morning was huge for us and we all know how important it is to get off to a good start. We know how strong the United States were in foursomes.
"3-1 was a great start, and the top two especially were such good momentum and inspiration for our boys. The guys grinded to win the session again this afternoon. That's another tick in our box, and I'm very happy where we are."
Team USA captain Keegan Bradley:
"The boys played really good this afternoon. Europe made a lot of putts. Happy with the way we're playing. Hopefully it'll turn and our putts will go in tomorrow.
"We've only played 28 per cent of the points. This is first quarter. We've still got three quarters to go. I've got a lot of faith in my boys."
