The 2017 US Open field of 156 players is made up of 72 players who get into the tournament through sectional qualifying, which finished on June 5. As part of the sectional qualifying process, the USGA also identifies US Open alternates from each of the 12 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 12, the week of the championship. The USGA left six spots available for that possibility. However, only two players can be replaced in the top 60, meaning there will be four spots for alternates.
Phil Mickelson has indicated that he will not play in the US Open so he can attend his daughter's high school graduation. That's a fifth spot.
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 full list of 2017 US Open alternates from the sectional sites.
So far, Michael Putnam, Gregory Bourdy, Tyler Light, Davis Love IV, Meen Whee Kim and Ryan Palmer have gotten into the field.
