Bryson DeChambeau, Russell Henley and Harris English have secured the final three automatic qualifying places on the US Ryder Cup team.
They join world number one Scottie Scheffler, US Open champion JJ Spaun and Xander Schauffele on captain Keegan Bradley’s team for next month’s contest against Europe at Bethpage, New York.
The six American qualifiers were confirmed following the conclusion of the last qualifying event, the BMW Championship, which was won by reigning US PGA Championship and Open champion Scheffler.
DeChambeau, who plays on the LIV Golf circuit, qualified thanks to three top-10 finishes in the majors this year.
Bradley will announce his six captain’s picks to complete the 12-man team on 27 August.
There is a chance that Bradley, 39, could pick himself to play after he finished in a tie for 17th at the BMW Championship, to cement 10th place in the US Ryder Cup standings.
Arnold Palmer was the Ryder Cup’s last playing captain, when he led the US team, aged 34, in 1963.
Justin Thomas and Collin Morikawa were among those to miss out on automatic qualification for the US team.
Ben Griffin, Maverick McNealy and Andrew Novak are the other three Americans in the top-12, but none have appeared at a Ryder Cup before and Bradley may opt for the experience of Patrick Cantlay, who is 15th on the list but has picked up 5½ points in two previous appearances.
Scotland’s Robert MacIntyre finished second to Scheffler in Maryland despite leading by four shots going into the final day.
But that was enough to see him join Rory McIlroy and Tommy Fleetwood in qualifying for the European team.
The other three automatic slots are currently filled by Justin Rose, Tyrrell Hatton and Shane Lowry with the standings finalised after this week’s British Masters at the Belfry.
Captain Luke Donald will make his picks for the six other places on 1 September.
One player who maybe in contention is former Masters champion Jon Rahm, who was crowned LIV Golf individual champion for the second consecutive year despite not winning an event.
LIV golfers can only qualify through ranking points earned through the four majors and Rahm is currently 23rd in the European rankings.
Europe will be aiming to defend their title when at the event from 26-28 September.
