So here is the list of courses scheduled to host the US Open, barring global warming, or other disasters:
2019 - Pebble Beach Golf Links, Pebble Beach, Calif.
2018 - Shinnecock Hills Golf Club, Southampton, N.Y.
2017 - Erin Hills Golf Course, Erin, Wisc.
2016 - Oakmont Country Club, Oakmont, Pa.
2015 - Chambers Bay, University Place, Wash.
2014 - Pinehurst No. 2, Pinehurst, N.C.
2013 - Merion Golf Club, Ardmore, Pa
So who is in the running to host the 2020 US Open?
Oakland Hills, Southern Hills, Congressional ?, Hazeltine (50th anniversary of 1970 US Open), Cherry Hills, (60 anniversary of 1960 US Open) .... somewhere in the South?, a new course? Trump course?
So who is not in the running? I would think that Bethpage Black, Torrey Pines (not going to have back to back West Coast Opens, Olympic Club, are not in the running for 2020.
