DUBLIN, Ohio — Jason Dufner spent quality time on the practice range that played in a big role in his victory at the Memorial.

It had nothing to do with his swing.

This was about beating balls to burn off the anger from a 5-over 77 in the third round that looked as though it might cost him the tournament. His pulse back to normal, which for Dufner means barely beating, he bounced back in a big way Sunday.

He stayed in the game during a wild stretch early, and then hit the ball so pure that he hit every green until the 18th and only once had a birdie putt over 12 feet. And then he capped off his 68 with a 30-foot par putt for a three-shot victory.

Dufner set the 36-hole record at Muirfield Village on Friday and built a four-shot lead. The 77 on Saturday dropped him four shots behind. And he wound up winning by three shots over Rickie Fowler and Anirban Lahiri.
