Phil Mickelson admitted it’s “not been his best month” as he continues to be asked about his US Open mishap at the Scottish Open.
The 48-year-old American played a moving ball at Shinnecock, stopping it rolling away from the pin, which earned him a two-stroke penalty.
Speaking at the Scottish Open, he said: “I've had a rough month. I haven't been my best. So I'm working at trying to fix that.”
“Oh sure, I made a big mistake and I wish I could take it back but I can't. Yeah, it wasn't a great moment and I wish I could take it back but there's not much I can do about it now other than just try to act a little better.
“Not only was I not great on the course, I was not great after the round, either. So it was just not a great day, and it was my birthday. So I tend to do dumb stuff on my birthday, too.
“The thing about this is throughout my career, 25 years, there have been a lot of times where I have had to be accountable for decisions I did not make.
"And the reason why this has actually been easier, it was my own fault. The backlash is my own fault. So it's much easier to deal with than some of the times where I have not been involved in the decisions and had to deal with that.”
The left-hander found himself slapped with another penalty at last week’s PGA Tour event, after patting down some grass at the front of a tee box which was classed as improving the lie.
