Video: 'The dumbest hole I've ever played in my life' - Jordan Speith on 18th at Chambers Bay
Nine-time major winner Gary Player labelled this week's US Open the "most unpleasant" tournament he has ever seen as criticism of Chambers Bay intensified on Saturday.
Masters champion and joint leader Jordan Spieth called the 18th "unbelievably stupid" when played as a par four when he was caught making the comments after making a double-bogey on Friday.
Henrik Stenson compared the greens to "putting on broccoli" - a point he illustrated in typical fashion with a picture on Twitter suggesting he was having broccoli for lunch.
World number one Rory McIlroy joked the putting surfaces were not green enough to be broccoli - "They are more like cauliflower" - and said he was delighted to have already secured one US Open title.
