Players and Qualifying

These criteria include things such as being a past champion or recent winner of another senior major, money leaders and points leaders from the Champions Tour, and winners of select USGA amateur championships if age-eligible.Golfers who do not meet any of the exemption categories can attempt to play their way into the U.S. Senior Open through local qualifiers and/or final qualifiers, 18-hole and 36-hole, respectively, qualifying tournaments played around the United States leading up to the Senior Open.
