The United States remain well in control of the Ryder Cup after they dominated Saturday's foursomes, in the process extending their overall lead to 9-3. 

It was certainly the home team who had been on top on Friday at Whistling Straits, and they refused to relinquish their grip by taking three points out of four available in the opening session on day two. 

USA's six-point advantage is the largest any side has held after three sessions since 1975. 

Spaniard Jon Rahm and compatriot Sergio Garcia – who also won on Friday – got Europe's solitary point, as they came from behind to overcome Brooks Koepka and Daniel Berger despite initially going three holes down. 

"It means a lot, it is a long race. We were three down early. If there is any point you want to be three down it is then because you have 15 holes to make it up," Rahm told Sky Sports. 

"We got going starting on the sixth when we woke up and that's when we started playing some good golf. 

"Besides a couple of mistakes here and there in the windy conditions and the cold we played unbelievable from six on and took advantage of the moments we had and a couple of breaks our way to win." 

Yet Europe did not have any further joy in the remaining matches. 

The rookie duo of Viktor Hovland and Bernd Wiesberger made some early inroads, yet Jordan Spieth was in inspired form as he combined with Justin Thomas to triumph, aided by taking four of the last five holes. 

"Getting to three down is tough, at two down you can go on a quick run, but three down the percentages go way down," Spieth told Sky Sports. 

"Luckily it was only through six, we knew we would have a chance in this wind, those guys had a few putts they missed that Sergio and Rahm holed yesterday. 

"We felt like we played good golf for two rounds and deserved at least one point." 

Paul Casey made a superb chip-in from distance as he and Tyrrell Hatton made a charge on the back nine, yet Dustin Johnson and Collin Morikawa remained out of reach for the duo. 

Xander Schauffele and Patrick Cantlay won for the second consecutive day to cap off a brilliant morning for the Americans, winning holes nine, 10 and 11 to really take control as they overcame Lee Westwood and Matt Fitzpatrick.
