The 2025 US Open field of 156 players is made up of approximately 50 players who get into the tournament through sectional qualifying, which finished on June 2. As part of the sectional qualifying process, the USGA also identifies US Open alternates from each of the 13 sites.
The USGA will pull from the US Open alternate list to fill the field of 156 players, with the governing body allocating exempted spots for players who may get into the top 60 in the Official World Golf Ranking as of June 10, the week of the championship. The USGA left six spots open for that possibility, which are filled by alternates in the evnet the players in the RBC Canadian Open don't hop into the top 60.
After the RBC Canadian Open, Takumi Kanaya, Doug Ghim, Chase Johnson, Eric Cole and Riki Kawamoto were all added to the field after Ryan Fox, Cameron Young and Bud Cauley got into the field via the OWGR top-60 cutoff.
Then there are all the players that could potentially withdraw the week of the US Open with injury or other problems.
The USGA doesn't produce a US Open alternate list with a specific priority order in mind. They keep that a secret and contact alternates at their discretion as spots become available. However, here's the top of the list of 2025 US Open alternates from the sectional sites.
