Tiger Woods has been named as one of Davis Love III's vice-captains for the 2016 Ryder Cup.
Love had previously named Tom Lehman as the first of his five vice-captains upon his appointment as USA team captain in February, and he has now added Woods, Jim Furyk and Steve Stricker to his ranks.
Furyk has played in nine consecutive Ryder Cups, second only to Phil Mickelson in USA's history, while Stricker was also a vice-captain during the tournament at Gleneagles last year.
"To welcome four vice-captains of this calibre is a giant first step towards preparing the 2016 team for success," Love told reporters.
"Tom, Jim, Steve and Tiger have over 50 years of combined Ryder Cup and Presidents Cup experiences that they are eager to share. They'll also be my eyes and ears from event to event next year on Tour.
"That's invaluable and, as captain, I am grateful for their commitment, dedication and passion to win."
The 2016 Ryder Cup will take place at the Hazeltine National Golf Club in Minnesota, with USA looking to win the trophy for the first time since 2008.
