Gary Player described it as "the most unpleasant golf tournament I’ve seen in my life".
Henrik Stenson said of the greens, "it was like putting on broccoli".
Sergio Garcia tweeted his dissatisfaction with the greens also.
I think a championship of the caliber of @usopengolf deserves better quality green surfaces that we have this week but maybe I'm wrong!

And now, speaking with Sky Sports, Lee Westwood has also been highly critical Chambers Bay, the course hosting this year's US Open.
Westwood's main problem was with the 'tricking up' of the course.
My main criticism of the golf course this week is that it's a pretty solid test, fair in most places. So why bother tricking it up and changing holes around and the pars of holes and things like that.
Just lay a golf course out and let everyone play it and see who comes out on top.
We actually played the 15th hole yesterday at 144 yards and it was from a tee that I didn't even know existed.
It didn't even look like a tee. We'd played it from 235, which it's played today I believe and from about 170 which it played the first day.
Then all of a sudden they throw a tee down in the middle of nowhere.
That's my main criticism of it. I don't see how why they're jiggling it around so much and messing with the players' preparation.
If you're going to change tees around like that then you do need 15 practice rounds but some of us don't have the luxury of that.
The Englishman called it ridiculous that on some holes, spectators were unable to actually watch the golf.
They say eight years ago that this golf course was designed for the US Open.
Yesterday, the two longest holes on the golf course, the eight and the first hole - you can't actually get any crowds around these two holes.
How ridiculous of a design is it where you designed it for spectators and they can't get into a position to watch the golf.
Asked if his sentiments were being echoed by other competitors, Westwood felt that many were afraid to say what they really think.
Most players are too afraid to say what they think and certainly from people in the media, they're a little bit afraid aswell.
We're living in a politically correct world where people can't voice opinions now.
I think if you had a hidden camera and a microphone in the locker room you'd hear a few things that you're not hearing in public.
