"As Fownes so [pointedly] said--let the clumsy, the spineless and the alibi artists stand aside!"
I don't believe that this quote is nearly as well-known as "A shot poorly played should be a shot irrevocably lost"
Before I speculate, understand that Baltusrol, Whistling Straits, Oak Hill and Bethpage are now in the PGA of America (PGA, Senior PGA, Women's PGA, Ryder Cup) camp and are no longer (for the time being) candidates for USGA championships.
What we know:
2017 -- Erin Hills
2018 -- Shinnecock Hills
2019 -- Pebble Beach
2020 -- Winged Foot
2021 -- Torrey Pines
2022 -- The Country Club
2023 -- Los Angeles Country Club
2024 -- Pinehurst No. 2
2025 -- Oakmont Country Club
2026 -- Shinnecock Hills
I think that a 2030 US Amateur at Merion is more likely than the US Open returning there between 2027 and 2030. I think that Chambers Bay will get an Open either in 2028 or 2029. A dark horse is Sebonack; even though the Open is in the Hamptons in 2026, I think that the course has enough teeth and expandability to host a men's championship (and lord knows, the owner has clout.) Unless I missed some news bulletin, the Women's Open of 2013 was well received.
There has to be a midwestern US Open (Pittsburgh doesn't count) in that four-year stretch. The diviners who mention Oakland Hills are astute; they have been a PGA Course for a bit (last in 2008). Here are the upcoming PGA sites:
2017 -- Quail Hollow (Charlotte, N.C.)
2018 -- Bellerive (St. Louis, Mo.)
2019 -- Bethpage Black (Long Island, N.Y.)
2020 -- TPC Harding Park (San Fancisco, Calif.)
2021 -- Kiawah Island, The Ocean Course (Kiawah Island, S.C.)
2022 -- Trump National Bedminster (Bedminster, N.J.)
2023 -- Oak Hill Country Club (Pittsford, N.Y.)
If Oakland Hills wants a US Open and the restoration is in line with what the Mike Davis trio values, I think that they get it over Olympia Fields. The fact that this year's US Amateur is at Oakland Hills is a hint that the Detroit-area club wants to get back to Camp Nou (Jersey).
By a nose, I think that the PGA of America is more forward thinking, more radical, in its site selection for the marquee event, than is the USGA.
Here are my predictions:
US Open
2027 -- Oakland Hills
2028 -- Chambers Bay
2029 -- The Country Club
2030 -- Olympic Club
