Bernhard Langer has hit back at critics who still believe he is anchoring his putter against his sternum - a rule that was outlawed by golf's governing bodies in January 2016.
Langer, 59, admits the comments he has received over recent months, in particular from golf analyst Brandel Chamblee about his current style of putting, have been "hurtful" as he prepares to win a hat-trick of Senior Open titles at Royal Porthcawl this week.
Especially given the USGA has come out and defended Langer's method.
"I personally don’t understand it," Langer told The Telegraph, "because I’m a man of integrity, and the last thing I want to do is break rules and be known for cheating.
"I’m not touching any part of my body, and I know I’m within the rules. I have conferred with the rules officials on a regular basis, and they have wholeheartedly said, 'You’re not breaking any rule.' You have a few people who question my integrity, which is really hurtful."

Langer has enjoyed one of the best years of his over-50 career, winning three times (including two majors, which pushed him past Jack Nicklaus for the most senior majors all time), finishing second twice and posting four other top-10s in 12 starts.
With more than $2 million in earnings, he is more than $600,000 ahead of McCarron on the money list.
Langer believes his success on the Champions Tour has stuck a target on his back.
"It’s human to be jealous, let’s put it that way," said Langer.
"If I was 180th on the money list, I don’t think anybody would be talking about it. But I’ve been No. 1 the last few years."
