DUBLIN, Ohio (AP) -- Jason Dufner made a 3 on a par 5 and a 5 on a par 3. That was before he made a hole-in-one.
A wild back nine sparked Dufner to a 5-under 67 on Friday and left him one shot behind David Lingmerth of Sweden midway through the second round of the Memorial. Lingmerth had a bogey-free 65 and already has 14 birdies over two rounds at soft Muirfield Village.
Lingmerth was at 12-under 132.
Dufner didn't have much to say, speaking only to Ohio-based reporters. But he has never had a stretch like this.
