The U.S. Open concludes Sunday at Winged Foot Golf Club in Mamaroneck, New York, which has largely featured the sport's best struggling in windy conditions on a course with tight fairways, thick rough and confounding greens.
Only three players entered Sunday under par, led by 21-year-old Matthew Wolff at five-under. No golfer has shot under par in each of the first three rounds, and Bryson DeChambeau is the only one to shoot under par or better each day through 54 holes.
Leaderboard swings have been commonplace: Wolff trailed the lead by one after Thursday before falling four back Friday, but he entered Sunday two ahead of the entire field.
