Europe captain Thomas Bjorn said: "We'll enjoy this afternoon for a few hours, but then we'll focus on tomorrow". While Casey and Hatton were making all the important putts, both Fowler and Johnson struggled significantly on the greens.
The Europeans have now won eight of the last nine matches at this Ryder Cup after trailing 3-0.
Thomas and Spieth, the latter of whom has been the Americans' best player at this Ryder Cup, took a 1 up lead with a birdie at 2 but found themselves down 1 after 7. We go again this afternoon, that is what we are here for.
All eyes were then fixed on the fourth match of the day where Americans Jordan Spieth and Justin Thomas held off Ian Poulter and Jon Rahm 2&1 to stem the bleeding and keep the USA clinging to Europe's coat tails ahead of the foursomes.
Poulter held his nerve over a six-footer on the sixth after Spieth's handsome approach to within a few feet had opened the door for the Americans, and then produced a characteristic slice of Poulter Ryder Cup magic with a sensational putt from right across the seventh green to put Europe up for the first time.
The European train keeps rolling with an easy win.
The experienced duo of Poulter and four-time major victor Rory McIlroy battled back from 2-down to beat Bubba Watson and Webb Simpson 4 and 2. He didn't make his first (and only) birdie of the day until 9, hit multiple shots way off line including out of bounds and had none of the cocky swagger he displayed at Hazeltine. Garcia and Noren were antsy after sitting in the morning and just steamrolled to the easiest of wins.
Manchester United lose 1-3 to West Ham to deepen Mourinho woes
Asked if it was a good idea to confront Pogba in front of the cameras, Mourinho said: "I don't care about the cameras". It is their third loss in seven league games and follows a home Carabao Cup exit to Championship side Derby .
Another blowout, this one to cap a European clean sweep of the session. Rahm - who found the water three times in the first two holes - cut the lead with a birdie on the 12th.
Finau made the birdie putt to square the match, and Koepka's par was good enough to win the 18th for a 1-up victory. McIlroy played horribly the whole time and failed to make a single birdie.
"On top of it, I felt like I was in control kind of my golf swing". Fleetwood holed a 15-foot birdie from the fringe for the lead, and then the Englishman made a 35-footer on the next hole.
Match three looked set to finish in record fashion when controversial wild card Sergio Garcia and rookie Alex Noren raced seven up on Phil Mickelson and Bryson DeChambeau after just nine holes, but the European pair eventually had to settle for a 5&4 success.
The Americans won Nos. At one point, the USA led one match, trailed another and the other two were tied. Fleetwood's putter was on fire down the stretch in a match Europe had to have.
Rose and Rahm took a 2-up lead after some sparkling play around the turn, but lost the momentum as Koepka and Finau drew level with two holes to play.
