Jim Furyk, Steve Stricker, Brandt Snedeker and Dustin Johnson have been selected by Davis Love III to complete his United States Ryder Cup team.
The quartet are Love's choices for his captain's wild card picks for the match against Europe at Medinah, near Chicago, which takes place between September 28 - 30.
Love said: "I can't tell you how excited I am that these four guys are going to round our team out. I think we're extremely deep this time, deeper than we've ever been."
The four players selected will join the eight already qualified via the points list for the match. They were Tiger Woods, Phil Mickelson, Zach Johnson, Bubba Watson, Matt Kuchar and rookies Jason Dufner, Keegan Bradley and Webb Simpson.
Snedeker is a fourth first-timer on the USA team, while Johnson is playing in the event for the second time after featuring in 2010's defeat at Celtic Manor.
Love told a press conference: "We need hot putters and there really hasn't been a hotter putter on tour since the Open (than Snedeker). He brings lot on and off the course and to the team room, he can pair with anyone, he's a great asset.
"(Johnson is) the best athlete on the team and he's perfect for Medinah. I said I was going to try to plug some holes we had, and I think he does that."
On veterans Furyk and Stricker, making their eighth and third appearances respectively, he added: "We also needed experience, Jim is one of the most consistent players on the tour and one of the most respected.
"I've been in the team room with him five times, this will be his eighth team and he was 5-0 in his last international match (the 2011 President's Cup).
"(Stricker has) been the best player in my mind on tour the last five or six years. He's another guy that pairs well with anybody and another great putter, and he's somebody I really trust on and off the course - he's been a great asset to me already getting prepared for this day."
