PONTE VEDRA BEACH, Fla. – Keegan Bradley said his 1-under 71 in the second round of THE PLAYERS Championship on Saturday was one of the best performances of his life, given the stiff winds and chilly temperatures.

It could have been better.

Facing a birdie putt from 10 1/2 feet at the par-5 16th hole, Bradley put his marker behind the ball but had not picked up the ball when a sudden gust of wind blew it across the green. Thinking he had officially marked the ball, he returned it to its original spot, missed the birdie putt, and tapped in for a par.

Or so he thought. He had made the turn and was on the second hole when Chief Referee Gary Young told Bradley he had broken Rule 9.4 a. Because he had put the mark down but not picked up the ball, he had not officially marked his ball when it was moved by an outside agency. As a result, the Rules of Golf state that he should have played the ball from where it stopped rolling, not return it to its original position.

Bradley was told he was being assessed a two-shot penalty, his par turning into a double-bogey. It would be his only over-par hole in a round that included birdies on holes 2, 13 and 15.

“Everyone in my group, and I guarantee most of the entire field, thought the USGA changed the rule to simplify it,” Bradley said. “Put your coin down, that's where your ball is. So put my coin down, the ball moved, a huge gust of wind came up.

“I looked at the guys in my group,” he continued, “and we all said, yep, the coin was down first, all good. Didn't think about it again until Gary came up and spoke to me on 2, and proud of the way I handled that because that was tough news, especially with some tough holes in front of me.”
