DUBLIN, Ohio -- One day later, not much changed at the Memorial on Saturday. Carl Pettersson had a one-shot lead, storm clouds gathered and players walked off Muirfield Village knowing they would have to resume the third round at the crack of dawn.

But it was far from an ordinary day.

Two players who had been disqualified Friday evening for leaving the course before play was suspended were allowed back into the tournament when officials decided they were given bad information.

Jay Haas hardly showed his age. The 52-year-old Senior PGA champion played 33 holes because of the rain delays, tying a PGA TOUR record by making his 590th career cut, then shooting an even-par 72 in the afternoon.

The hole location on the sixth hole changed in the middle of the second round when someone defecated in the cup overnight.

With nothing to lose, big-hitting Bubba Watson gave the gallery something to remember. He pulled out his pink-shafted driver on the 363-yard 14th hole and drove the green, a 352-yard drive that left fans stunned.

Masters champion Phil Mickelson surged into the lead with a 50-foot eagle putt and a chip-in from 25 feet off the green, only to give it back with a wedge that landed well behind the pin, spun to the front of the green and rolled into the water on the par-5 11th, leading to double bogey.

Woody Austin nearly made double eagle on the par-5 15th, settling for a tap-in eagle that thrust him into contention.

The only thing this tournament needs now is a conclusion.

Pettersson went about his business with pars and made birdies on the par 5s to reach 11 under, getting up-and-down from a trough in the bunker on No. 15 for birdie to keep his nose in front of Austin and Zach Johnson.

Austin was 6 under for the round when he hit out of a fairway bunker on the 18th to the front of the green. He's only 30 feet away but faces a difficult putt to get close when he returns at 7 a.m. Johnson rebounded from back-to-back bogeys with back-to-back birdies on the front nine, then ran off four straight birdies and joined Austin at 10 under through 16 holes.

The entertainment, as usual, belonged to Mickelson.

Starting a three-week stretch that will take him through the U.S. Open, Mickelson looks much sharper than he did when returning from his two-shot victory at the Masters, his second straight major title.

Mickelson thrust himself into contention with a two-putt birdie from the fringe on the par-5 fifth, a flop shot from a buried lie to save par on No. 6, and a brilliantly played seventh hole that shows why few can match his talent.

With the pin on the right of the green on the par 5, Mickelson hit a hard draw so that his ball would approach into the fat of the green without running through into thick rough or coming up short into a bunker. Then came the putt, so pure that he started walking when it was halfway there and thrust both arms in the air when it dropped on the final turn.

Then came the thrills.

He missed the green to the left at No. 8 for bogey. He pulled his tee shot into the trees on No. 9, played out of a muddy, shaggy lie short of the water and spun back a wedge to a foot to save par. He chipped in for eagle. He went into the water for double bogey. He saved par from left of the green at No. 12. Then a 6-foot birdie on the 13th, and a three-putt from the fringe for bogey at No. 14.

On and on it went, Mickelson looking confident or agitated, depending on the score.

Most frustrating of all had to be the siren that sounded after belting his tee shot in the middle of the 18th fairway. Mickelson was at 8 under, along with Adam Scott, who had three holes remaining.

There were 24 players who didn't finish the third round, and TOUR officials said the third round would resume at 7 a.m. -- about 11 hours after the siren sounded.

"I had just finished 15 and I looked up and I saw it coming," Pettersson said. "I don't know where it came from."

He'll find out where he's going on Sunday, with more at stake than just a prestigious title on the PGA TOUR and a handshake from tournament host Jack Nicklaus. Pettersson is No. 51 in the world ranking -- the top 50 are exempt to the U.S. Open -- so he planned to spend Monday playing 36 holes in a U.S. Open qualifier.

A victory would be his second since the last U.S. Open, giving him a free pass to Winged Foot.

"I'm just going to try to play and see what happens," Pettersson said. "If I have to go to qualifying on Monday, I'll go."

Ryan Moore and Justin Rose were told by their walking scorer Friday night that play had been suspended, so they left the course and were disqualified. They stated their case Saturday morning, and officials let them back in.

Moore was only five shots behind Friday evening, but a 74 in the third round left him 11 shots behind. Rose, however, shot 67 in the afternoon and is at 3-under 213.

"It was a tough decision, but I think it was the right call," Rose said.
