Jack Nicklaus earned the biggest payday of his career and equaled the course record for the second straight day, winning the $1 million Senior Tournament Players Championship by six strokes over Lee Trevino yesterday in Dearborn, Mich.

Nicklaus shot another eight-under-par 64 for a total of 261, 27 under par, on the 6,665-yard Dearborn Country Club course. He won $150,000. His previous best was $144,000 for winning the 1986 Masters, his last PGA Tour victory. Nicklaus has career earnings of $5,454,964

It was his second triumph in three Senior PGA Tour events. In April Nicklaus won his debut, the Tradition, then finished sixth in the Masters a week later. The U.S. Open, which he has won four times, begins Thursday at Medinah, outside Chicago.

Entering the Senior TPC, Nicklaus had played only four competitive rounds in seven weeks. He hadn't planned on coming and was the last player entered.

Nicklaus was pressured by the Senior PGA Tour and Ford Land Development Corp., for which he designed TPC Michigan, the course three miles away that will become the permanent home of the tournament.

The event is one of three senior majors, the richest and, at 72 holes, a rarity on the tour.

Nicklaus began the final round three stokes ahead of Trevino, his playing partner. But on Nos. 3, 4 and 5, he went eagle-birdie-birdie to pull away.

Nobody came close to the two superstars. Charles Coody and Jim Dent tied for third at 16 under, five shots behind Trevino.

Larry Ziegler broke the course record with a 64 Saturday and Nicklaus duplicated the feat later in the day.

Western Open: Wayne Levi birdied the first two holes and never looked back in Oak Brook, Ill., winning his second PGA Tour event in three weeks.

Levi, the third-round leader virtually unchallenged after his fast start, shot three-under 69 to finish at 275, tying the Butler National Golf Club course record set last year by Mark McCumber. It was the ninth title in 14 years for Levi, who broke a five-year winless string two weeks ago in Atlanta.

And the victory over the strongest field of the year -- 89 of the top 100 money-winners started -- stamped Levi as a favorite in the U.S. Open.

"The way you had to play here, the way you had to grind, it was a good test for the Open," Levi said.

Payne Stewart took second with a closing 72 for 279. He has two wins and two seconds in his last six starts.

Levi began the final round with a one-stroke lead, led by three after two holes and by as many as six on the back nine.

Tom Watson, second alone and three shots off the lead after 15 holes, lost five shots to par over the last three holes. Winless in three years, Watson bogeyed the 16th and 17th and hit two into the water on the 18th to finish with a triple-bogey 7.

Scandinavian Open: Craig Stadler shot an incredible 11-under 61 in Stockholm, shaving three strokes off the Drottingholm Country Club course record and winning by four strokes over Craig Parry of Australia (67 -- 272).

Stadler opened with four of his nine birdies and finished with an eagle on the par-5 18th. "I was hitting the ball very good, which I hadn't been doing for the last three years. My putting was also very good," he said.

McDonald's Classic: Patty Sheehan shot one-under 70 to win the LPGA event by four strokes in Wilmington, Del. With par or better on 61 of the final 62 holes, she finished at 275 on the 6,366-yard DuPont Country Club course.

Defending champion Betsy King, Ayako Okamoto, Kristi Albers and Cathy Gerring tied for second.

The victory was the second of the year for Sheehan, who won the Jamaica Classic, and her 22nd in 11 years.
