Lingmerth leads Dufner midway through Memorial


Thanks to a 7-under 65 Friday, David Lingmerth has vaulted to the top of the leaderboard at the Memorial. Here's how things stand through 36 holes at Muirfield Village.

Leaderboard: Lingmerth (-12), Jason Dufner (-11), Andy Sullivan (-10), Hideki Matsuyama (-9), Jim Furyk (-9), Francesco Molinari (-9), Brendon Todd (-9), Justin Rose (-9)

What it means: Lingmerth has missed four of his last five cuts but rounds of 67-65 have him halfway to what would be his first PGA Tour victory. He opened with six straight pars in Round 2 before rattling off three straight birdies on Nos. 7-9 and adding four more after the turn. He's played his last 30 holes a bogey-free 14 under. At No. 212 in the world, the 27-year-old Swede's best finish this year was a tie for 13th at Bay Hill in March. This is his first 36-hole lead on Tour.

Round of the day: Sullivan's 64 was the low number of the day and ties for the low round of the week. He played both the front and back in 4-under 32, navigating both sides without a dropped shot.

Best of the rest: Dufner followed up his roller-coaster 66 on Thursday with a wilder 67 on Friday. Starting on the back, he went out in 33, carding three pars, two birdies, two eagles (including an ace), a bogey and a double. The eagles came back to back, on the par-5 15th and par-3 16th. After his colorful opening nine, Dufner settled down on the inward half, with two more birdies and seven straight pars. Through 36 holes this week, Dufner has made four eagles.

Biggest disappointment: Local resident and Muirfield member Jason Day missed an 8-footer for par on the 18th green to shoot a second-round 72 and miss the cut by one at even par. Day's fate was sealed when Tiger Woods, playing with Day and putting right after him, holed a par putt to keep the cut at 1 under. Other notables to miss the cut include Rickie Fowler, Gary Woodland and Justin Thomas. Woods posted a 2-under 70 to make the weekend on the number.

Shot of the day: Dufner's hole-in-one from 201 yards on 16 capped off a birdie-eagle-ace stretch for the 2013 PGA champ, who sits one back.

Storyline to watch heading into the weekend: Rose has a history of success on classic northern courses - Aronimink, Merion, Congressional, Cog Hill - and claimed his first PGA Tour victory at Muirfield back in 2010. He sits just three back, along with two others who have previously won the Memorial in Furyk and Matsuyama.
