Warren Bennett was left cursing a bad start as he slipped to a five-over par third round score of 75 at the 141st Open Championship.
The rejuvenated Kent golfer bogeyed three of the first four holes as he carded his worst round of the week and is now six over.
"I just didn't play very well," the 40-year-old told BBC Radio Kent.
"It was perfect weather. It was just my golf that wasn't. Hopefully tomorrow I can fight and shoot under par."
Paired with American Dustin Johnson, last year's Open runner-up, Bennett said: "He played very quickly, which I like and it was good to get the chance to see him up close. He's certainly long off the tee.
"But he played like I did on Friday, putting it in the centre of the greens and making it look easy, while I was making it look hard.
"I hit some poor shots early on, missing greens on the short side which gave me no shot into the flags and before I knew it I was three over."
Another dropped shot followed at the 12th and, although Bennett then birdied 13, he dropped two more - at 15 and 18 - to finish six over for the championship.
Playing his first Open in 10 years as he sets out on a journey that he hopes will ultimately lead to him winning back his tour card, Bennett would love a good closing round on Sunday.
And he hopes that changing his putter might do the trick.
"I played steady without holing any putts later on," he added. "And I'm going to change my putter as I haven't really holed anything all week."
