Dufner sets Memorial Tournament record

Jason Dufner set a 36-hole course record at the Memorial Tournament for a commanding five-shot lead.

Dufner shot a second successive 65 in the final warm-up event for the US Open after sinking five birdies and a stunning eagle at the 18th.

The American’s approach chip at the 18th was the shot of the tournament so far after he pitched it high towards the pin, before the ball rolled back into the hole.

Birdies in three of his final five holes saw Dufner move to 14 under and beat the previous halfway best at the tournament by a shot.

"I did everything pretty well," said Dufner.

"I made some nice pars and rolled in some putts. But we've got two more rounds to go. We'll see how the course changes if the wind picks up, gets running fast, it plays different. We'll just see.”

Daniel Summerhays is Dufner’s closest challenger after he hit three birdies in four holes during a round of 69, although the deficit was extended to five following a bogey on the last.

Rickie Fowler is six adrift of Dufner after a classy 66, which included birdies on the final three holes.

Jordan Spieth, Jamie Lovemark and Justin Thomas are all two shots further back.
