Kohler, WI (My Sportsbook) - Tiger Woods and Phil Mickelson will need massive comebacks if either is to walk off with the PGA Championship on Sunday.

In Saturday's third round, Woods, a four-time PGA champion, birdied his last two for an even-par 72. He is through 54 holes at three-under 213, but that puts him two ahead of Mickelson, who had a 73 in the third round.

Nick Watney is the leader at 13-under par.

"It was a struggling day and I'm done with it," Woods said in a television interview. "I didn't make any putts early and didn't gain any momentum. Tomorrow I want to go out there and play a good round and see where that puts me."

Woods had to return Saturday morning to finish his second round. Lengthy fog delays each of the first two days pushed the tournament back, but it's on schedule as of Saturday.

Woods played poorly on the front nine with three bogeys. He birdied 11 and 14, but a bogey at the par-five 16th left him two-over for the round and one-under for the championship.

Despite the huge deficit, Woods was able to joke about his prospects on Sunday.

"People have shot 50s before this year," joked Woods, referring to the 59s this year from Paul Goydos and Stuart Appleby.

Woods has certainly been better than last week. At the WGC-Bridgestone Invitational, Woods finished 18-over par and tied for 78th in the 80-man field. Both the position and score in relation to par were professional worsts, so this has been an improvement.

"I feel so much better, how I'm hitting the golf ball now," said Woods. "The striking, the sound, the feel, more than anything, it feels good."

At the par-three 17th, Woods stiffed his approach a foot from the hole. He kicked in the short birdie putt, then rolled in a 25-footer for birdie at the last to get to three-under.

Mickelson, who won this title in 2005, began on the 10th tee in round three. He mixed a birdie and a bogey over his opening nine and traded two birdies and two bogeys through the first eight holes of his second nine.

Mickelson missed a lengthy par putt at the ninth to make bogey and fall to minus-one.

WHO IS WEN-CHONG LIANG?

The short answer is: Wen-Chong Liang is new holder of the competitive course record at Whistling Straits after his eight-under 64 in Saturday's third round.

"Today the driving, also putting are all very well and so it makes the whole round very good," Liang said through an interpreter on Saturday. "The other thing is I know to remain calm, not let the major pressure get to (me). So I'm able to perform very, very well today."

The Chinese golfer is tied for fourth place at nine-under par after three rounds. Liang is ranked 78th in the world and is playing in his second PGA Championship.

Liang hasn't won a PGA Tour event yet, but did prevail on the European Tour in 2007 at the Singapore Masters. He became the second Chinese-born player to win on that tour.

So Liang is a world-class golfer, but he didn't get started until his teenage years. Golf wasn't a huge sport in China when Liang was growing up

"I started when I was 15. My hometown, that's where the first golf course in China is," Liang said through his interpreter. "It was designed by Arnold Palmer and it opened in 1984. And really when they had that golf club they started this golf team. And I am considered the second generation of that golf team."

What may have made Liang's 64, which broke Darren Clarke's mark of 65 from 2004, even more amazing was that Liang underwent massive swing changes in recent years.

"I wish that coach Kel Llewllyn is here, but basically it's a total rebuild from stance to grip to take away to down swing, everything," he said. "Now I'm more relaxed and very comfortable with my swing."

* Senior PGA Champion Tom Lehman aced the par-three 17th hole on Saturday with a four-iron. The 1996 British Open winner shot a one-over 73 in the third round is in at plus-one.

* The second round was completed on Saturday morning after lengthy fog delays set the tournament back. The tournament dodged a bullet when much less rain came overnight Friday, so the second round was finished, then the players went out in threesomes off both the first and 10th tees in the third round.

* Rob Labritz was the only club professional to make the cut. He shot a two- over 74 in round three and is tied for 64th at plus-two.

* The par-four fourth remains the most difficult hole for the week. It is playing to an average of 4.51 and has netted only 13 birdies through three rounds of the tournament.

* The easiest hole is still the par-five fifth, which is playing to an average of 4.64.
