USA captain Tom Watson has admitted that he made his wildcard selections with a view of pairing them with their successful partners from the 2012 Ryder Cup.
Watson has admitted that he has had these pairings in mind when handing out his three wildcards and hinted that he would look to utilise the "great chemistry" of the quartet on Friday and Saturday of this week.
"A part of me, when I chose the captain's picks, was about chemistry," he told reporters. "Obviously Webb Simpson and Bubba Watson have good chemistry. Also Keegan Bradley and Phil Mickelson have good chemistry that they've shown in the past.
"You have to go back on past experiences. Also the way they're playing is a big factor as well. There's no one factor, it's a combination of factors."
