Team USA will take a 3-1 lead into the afternoon matches after winning three of the four morning foursome sessions.
In the first match – the marquee showdown, Spaniards Jon Rahm and Sergio Garcia teamed up to take down the USA’s top duo of Justin Thomas and Jordan Spieth, 3&1.
It was all-square through six holes with each pair taking two holes, but when the Spaniards reeled off wins on hole Nos. 7, 8, and 10, to go 3-up, it never got close again.
Team Europe closed it out with a par on the 17th to win the match 3&1.
The Americans came roaring back, though, taking all three of the remaining matches, rather easily, with no match even reaching the 18th hole.
Dustin Johnson and Collin Morikawa put the first points on the board for Team USA, edging Paul Casey and Viktor Hovland 3&2.
Xander Schauffele and Patrick Cantlay then made it 2-1 for Team America, easily routing Rory McIlroy and Ian Poulter, 5&3.
Finally, the Florida State pair of Brooks Koepka and Daniel Berger took down Lee Westwood and Matt Fitzpatrick, 3&1, to ring up America’s third point in the morning session.
