NEW YORK -- With the 2016 Barclays underway, three-quarters of Ryder Cup USA is on the verge of being set.

Five are already mathematical locks, according to the PGA of America. Dustin Johnson, Jordan Spieth, Phil Mickelson, Jimmy Walker and Brooks Koepka are in, and they await three more for the roster.

That will be set at the end of the Barclays.

The 46-year-old Mickelson will be making his 11th consecutive Ryder Cup start at Hazeltine National, Sept. 30-Oct. 2, which is a U.S. record. He has been a member of two winning U.S. teams -- 1999 and 2008 -- over that stretch, which covers 21 years dating back to Oak Hill in 1995.

"Having Phil Mickelson, who's made a record 11 U.S. teams, will be incredibly valuable," said Love, who was also the U.S. Captain at Medinah in 2012. "Phil will be a leader for us both on and off the golf course at Hazeltine National.

Dustin Johnson was the top point-getter for the U.S. over the past two seasons, thanks largely to his victories in two World Golf Championships (the 2015 Cadillac Championship and 2016 Bridgestone Invitational) and, most notably, his first major championship triumph in the 2016 U.S. Open at Oakmont. This will be Dustin Johnson's third Ryder Cup appearance overall and his first since 2012.

Spieth finished second to Johnson in points. Following a breakout 2015 season in which he won both the Masters and U.S. Open and finished among the top 4 in the Open Championship and PGA Championship, Spieth also snagged victories in 2016 at Kapalua and Colonial, while also finishing tied for second in the Masters.

Spieth compiled a 2-1-1 record, collecting 2 1/2 points -- second-best on the team -- in his Ryder Cup debut at Gleneagles in 2014.

Walker, winner of the 2016 PGA Championship -- his first major victory -- went 1-1-3 at Gleneagles, which was also his Ryder Cup debut. Walker joined Rickie Fowler as the only two Americans to play in all five sessions in 2014.
