The U.S. Open is open to any professional, or to any amateur with an up-to-date men's USGA Handicap Index not exceeding 1.4. Players (male or female) may obtain a place by being fully exempt or by competing successfully in qualifying. The field is 156 players.
In the event that 78 or more players make the 36-hole cut, then the PGA Tour has a secondary cut after 54 holes to reduce the field to the number nearest possible to 70 players. Those players who survive the secondary cut play the final round and have an opportunity to move up the leaderboard.
