Lehman, who qualified for the event by winning the British Open, set a Grand Slam record of 10-under-par 134 by shooting a 34 this morning at the Poipu Bay Resort to complete a second-round score of 66.
The previous record of 135 was set in 1991 by Ian Woosnam at Kauai Lagoons when the Grand Slam was first held on the Garden Island and became a 36-hole event.
Steve Jones, the U.S. Open champion, finished second at 136 for the $250,000 runner-up prize. Masters champion Nick Faldo was next at 139 for $200,000, while Mark Brooks, the PGA champion, was the only one not to break par, carding a3-over 147.
Because of Tuesday's rainout, 27 holes were played yesterday with the final nine being played today.
In contrast to yesterday's overcast skies, today saw brilliant sunshine without a breath of wind.
But none of the champions of golf's four majors could take advantage of the ideal conditions.
Lehman was the only one to get a birdie in the first eight holes, doing so on the par-4 10th when he sank a five-foot putt that gave him a two-stroke lead that held up the rest of the way.
Lehman and Jones, two close friends who will represent the United States in next week's World Cup in South Africa, finally got birdies on the par-5 finishing hole to finish one-two.
Faldo yesterday took an early lead by birdieing six of his first 12 holes under soppy conditions with casual water everywhere on the golf course following a four-inch downpour Monday night that delayed the event one day.
It was amazing that they got to play at all yesterday, let alone 27 holes.
The players were allowed to lift, clean and place their ball on the fairways. Another advantage was that they could fire at the flagstick because of the soft greens.
"It's target golf, right now," Lehman said.
"The morning was hard work. It was so wet," Faldo said yesterday. "I was on a roll and then I lost some momentum," said the three-time Masters and British Open winner.
"I just slowed down after that flyer on 13 and that bad three-putt on 16," Faldo added, referring to his two bogeys over in the first 27 holes.
Faldo three-putted the 16th again today, costing him a shot at overtaking Jones for second place.
"Nick gave us a break. He was running off with the whole thing after 12 holes," Lehman said.
Lehman took the lead to stay by rolling in a 10-foot birdie putt at the par-4 fifth - hole No. 23 - in the 36-hole event.
He went to eight-under, on the next hole, a 573-yard par-5, which he also birdied in the morning round as well.
When it was pointed out to Jones that the U.S. Open champion has never won the PGA Grand Slam - now in its 14th year - Lehman said teasingly, "All right!"
It turned out to be prophetic.
Brooks just had a bad day - unfortunately it came at a time when playing 27 holes was called for. He birdied his first hole of the day, but never recovered after four-putting the par-3 seventh.
Third on the 1996 money list with a career best of $1.6 million, Brooks had found some consolation despite finishing last. Fourth place was worth $150,000.
Jones made the best comeback in the afternoon nine yesterday with six birdies and a great bogey. Great because he had to sink an 18-foot putt after plunking his tee shot in the lake guarding the par-3 seventh hole - the one that Brooks had trouble putting earlier in the day.
"Great bogey," Jones agreed. "That could have been a double."
The players are miked for the made-for-television event on TBS. There was only one bleep - by Jones who used the F-word when he missed the green at the par-3 third hole in the afternoon.
"What'd I say?," said Jones with a straight face but a smile.
Not the most charismatic of Grand Slam foursomes, the three leaders enjoyed themselves despite the long day.
Jones, in particular, kept making a circle with both arms, an O sign, indicating a shot deserving of a standing ovation from the gallery, which included a small cheering section of his family.
"That's the way Steve is all the time. Jokes around and having fun," Lehman said.
But today, it was Lehman who had the most fun.
