Danny Willett says he is yet to decide whether back surgery will be required to fix his ongoing problem after another frustrating performance at the Open last week.

Willett sensationally claimed the 2016 Masters at Augusta National, making the most of a huge collapse from American Jordan Spieth, but the Englishman has been on a downward spiral ever since his sole Major triumph.

The 29-year-old from Sheffield has not won any tournament since the event in Georgia and his form in 2017 has been very poor, having missed the cut on five occasions while also being forced to withdraw three other times due to injury.

His confidence appears to be at an all-time low at the moment and the recent outing at Royal Birkdale for the 146th Open Championship has done little to lift his mood.

The five-time European Tour winner finished 76th out of the 77 players to make the cut in what was only the second time he has managed to play a full tournament since the BMW PGA Championship.

Willett is now looking into the possibility of going under the knife to fix the troublesome back problem although he doesn’t believe surgery is the answer at the moment.

“I don’t know. I’d do anything that helped,” he said. “I don’t think it does need surgery, it’s more just getting it in line and the only thing that irritates it massively is swinging poorly.”

The final Major, the US PGA Championship, takes place at Quail Hollow next month and Willett is a massive 201.00 outsider to win, while Open champion Spieth, who would complete the Grand Slam with another title, is priced at 8.50.
