Peter Jacobsen, still rehabbing from arthroscopic hip surgery, shot a 6-under 65 yesterday to take the first-round lead at the U.S. Senior Open in St. Louis.

Craig Stadler had a bogey-free round and was second at 5 under, and St. Louis area native Jay Haas birdied the final two holes to cap a 67.

Jacobsen, at 50 a Champions Tour rookie, had to withdraw from his past two events because of continuing pain from the hip surgery in April. Weeks on crutches caused his leg muscles to atrophy.

"Hitting the ball is no problem," Jacobsen said. "Walking 18 holes is the difficult part for me."

And it's a long walk. Bellerive Country Club, at 7,117 yards, is the longest course in the 25-year history of the Senior Open. Still, scores were low in favorable conditions, with little or no breeze, overcast skies and unseasonably cool temperatures for late July in St. Louis. Twenty players were within four shots of the lead.

Defending champion Bruce Lietzke shot a 4-over 75.

* BUICK OPEN: Vijay Singh shot a 9-under 63 to take the first-round lead in Grand Blanc, Mich., with Tiger Woods four shots behind.

Singh, one shot ahead of Olin Browne and two in front of Mike Grob, fell two strokes short of the tournament record.

Defending champion Jim Furyk shot a 66 and was tied for fourth with four others.

Woods got off to a slow start with one birdie through eight holes before closing with four birdies in eight holes.

* WOMEN'S BRITISH OPEN: Annika Sorenstam's strong start was not quite as good as Karen Stupples' opening round in Sunningdale, England.

Stupples made seven birdies in a bogey-free 7-under 65, putting her three shots ahead of defending champion Sorenstam.

Sorenstam was in a group of five players at 4 under.

* JUNIOR GOLF: Ji Ho Moon, 15, of Ellicott City, won the Independent Insurance Agent Junior Classic by five strokes in Ardmore, Okla.

After shooting 70-69-71 the first three days, Moon closed out the victory with an even-par 70, finishing with a 280 total to hold off second-place Allen Koon.
