PGA Championship 2013: Complete Analysis of Day 2 Leaderboard

Jason Dufner was one shot from history at the 2013 PGA Championship. Unfortunately he came up just short.

Dufner is the leader after two rounds, largely on the strength of his seven-under 63 on Day 2. It tied for the lowest round ever at a major tournament, per SportsCenter.

At the very least, he was able to set the course record at Oak Hill Country Club, per ESPN Stats and Info.

He picked up an eagle on the second hole with an outstanding third shot that set the tone for the rest of the round.

From then on, it was smooth sailing for the 36-year-old. He had a bogey-free 18 holes that also included five birdies.

Dufner, a graduate of Auburn University, got some praise on Twitter from the Tigers' football coach, Gus Malzahn.

Sitting at nine-under, Dufner is two strokes ahead of Adam Scott, Matt Kuchar and Jim Furyk.

You can see the leaderboard below.

Scott is a threatening presence in that three-way tie for second. He won the 2013 Masters and finished third at the The Open Championship. Given how strong Scott has been in the first two rounds, you can count on him staying close to the leaders the rest of the weekend.

Robert Garrigus shot himself in the foot on the final two holes of the round. He set a blistering pace on Day 2 by birdieing five of his first eight holes. Following a bogey on No. 9, Garrigus leveled off and managed to avoid too many mistakes on the back nine. Then, right at the end, he bogeyed both 17 and 18 to fall to five-under for the tournament, and four shots behind Dufner.

Before Dufner finished up, Webb Simpson had already tied the course record, with his six-under 64, per the Golf Channel's Kelly Tilghman.

Had it not been for a bogey on No. 7, Simpson could very have been right there with Dufner, as he had seven birdies on the day. As a result of his almost record-breaking performance, Simpson rose 65 spots from Round 1 to Round 2.

All in all, it was a pretty good day for the 28-year-old, even if he was overshadowed by Dufner. Given the way he performed on Friday, Simpson will be one to watch this weekend. At four-under for the tournament, he's well within shouting distance of Dufner at the top.

As with any major, the adventures of Tiger Woods demanded a lot of attention.

Woods was only slightly better on Day 2 after shooting a one-over 71 in the first round. He finished at even par for the day and finds himself in a tie for 38th at one over.

The par-four 14th hole was a good example of what has gone wrong for Tiger in the PGA Championship. He was able to drive the green with this great shot.

He subsequently had to three-putt and only picked up a par.

The entire day, Woods couldn't keep a sustained run going. He birdied the fifth and sixth holes, and then couldn't build upon that. He bogeyed No. 11, and then alternated birdies and bogeys for the final four holes.

This shouldn't come as a huge surprise, as Woods has yet to break par in any of the six rounds he's played at Oak Hill in PGA Championships, per ESPN Stats and Info.

One of the big risers on the day was K.J. Choi.

Coming into the second round, Choi was in 132th place, at six-over. He then posted a five-under 65 on Friday to get all the way up to 38th. The 43-year-old went from threatening to miss the cut to finishing in a rather comfortable position and looking to earn himself a nice payday this weekend. It's quite the turnaround over just one round.

If the next two days of the PGA Championship manage to be as entertaining as the first two, fans are in for a thrilling weekend.
