Peter Willett wrote an article in National Club Golfer magazine before the event which described American fans as a “baying mob of imbeciles”, “cretins”, and “dim Yanks”.
Danny Willett said before the start of play that it was “a bad article written at a bad time”.
Willett played poorly, as Europe slipped to a 17-11 defeat, which was marred by heckling from sections of the American support towards members of the European team.
“Very strange week here at the Ryder cup.. Tried my best but played poorly,” Danny Willett wrote on Twitter.
“Unfortunately some american fans showed that @P_J_Willett was In fact correct..
“Nothing to blame my bad play on.. But still shows that sometimes fans don’t know when to call it a day.. Shame really!!”
Danny Willett did not feature in the Friday morning foursomes and he was hammered 5&4 by Brooks Koepka in Sunday’s singles. He was also beaten in the Friday fourballs by Koepka and Brandt Snedeker alongside Martin Kaymer, while he and Lee Westwood lost by one hole to JB Holmes and Ryan Moore in Saturday’s fourballs.
Raucous crowds at Hazeltine heckled Rory McIlroy, in particular, as the hosts regained the trophy for the first time since 2008.
McIlroy admitted “a couple of people crossed the line”, but said that was “to be expected”, while Westwood and captain Darren Clarke praised the American team and staff for attempting to maintain order.
Willett also retweeted a post showing a video extract from his press conference.
Asked to describe his first Ryder Cup experience, the Englishman — seen with a can of lager beside him — emphatically responded: “Shit.”
That prompted laughter and even a high-five, before Willett added with a shrug: “I can only be honest. Sorry, would you like me to elaborate? Really shit.”
