The United States Golf Association (USGA) today announced groupings and starting times for the first two rounds of the 2015 U.S. Open Championship, Thursday (June 18) and Friday (June 19), at par-70 Chambers Bay, which will be set up daily between 7,200 and 7,600 yards.
The U.S. Open is a 72-hole, stroke-play competition. A field of 156 players will play 18 holes of stroke play on June 18 and 19, after which the field will be reduced to the low 60 scores and ties. Those players making the cut will play 18 holes on June 20 and 21. If there is a tie upon the completion of 72 holes, a scheduled 18-hole playoff will be played on June 22 at 9 a.m. If this playoff results in a tie, the tied players will immediately continue to play off hole-by-hole until the winner is determined.
