U.S. players will continue to gain points in 2018 at every non-opposite PGA Tour event, WGC and major through the 100th PGA Championship at Bellerive, concluding on August 12, 2018.
At that time, Captain Jim Furyk will have his first eight players -- automatic qualifiers.
The four remaining slots on the U.S. Team will be Captain's Selections. Three selections will be announced by Captain Jim Furyk following the Dell Technologies Championship scheduled to be completed on Sept. 3, 2018, and the final selection will be announced after the BMW Championship, which is slated to be completed on Sept. 9, 2018.
