Tournament officials admit it is "critical" this week's US Open passes without incident after being blighted by controversy in recent years.

The USGA admitted they went "too far" with the set-up of Shinnecock Hills last year after only three players broke par in a third round during which Phil Mickelson was penalised for hitting a moving ball as it rolled off the 13th green.

That followed problems with the greens at Chambers Bay in 2015, a controversial ruling involving eventual champion Dustin Johnson in 2016 and a course that was deemed too easy the following year.

Asked how important it is to avoid such problems at Pebble Beach, John Bodenhamer, the USGA's senior managing director of championships, said: "I think it's critical. We have talked about it all year.

"It's important for the USGA and for the game. We all feel a great obligation in that regard and we feel good about our plan." 

The rules issue in 2016 even prompted talk of a player boycott of the US Open, with Johnson and Rory McIlroy named among the players who considered such a move, according to a report in Golf Digest.

Asked about the report, USGA chief executive Mike Davis said: "I read it but we have decided to take the high road on it.

"We are focusing on this week and feel it's in everyone's best interest to move forward."
