DJ misses the cut as Dufner breaks 36-hole record

Jason Dufner shot a second consecutive round of 65 to record a new tournament record of -14 after 36 holes at Jack Nicklaus's Memorial course at Muirfield Village, Dublin, Ohio.

The highlight of Dufner's round was an eagle at the par-four 18th, his ninth hole, where his six-iron from 176 yards rolled to the back fringe doing a 180 and rolling back down the slope ad into the hole. Duf takes a five shot lead into the weekend.

Rickie Fowler posted a 66 to move into third place at -8, one behind Daniel Summerhays (-9). Jordan Spieth couldn't make any ground, however, shooting a level par 72 to remain at -6. Spieth's round was totalled after three bogeys on the front nine. Scotland's Martin Laird is a stroke further back at -5.

"We got two more rounds to go," said 40-year-old Duf. "We'll see how the course changes, if the wind picks up, gets running fast, it plays different. We'll just see."

Meanwhile, world number one Dustin Johnson missed the cut at +8. He was in good company. Billy Horschel (+5) and John Rahm (+6) also missed the cut. All of which makes Dufner's 36 hole score even more remarkable.
