GOLF ROUNDUP : Frost by 3, Gilbert by 6, and Sheehan Leads by 9

David Frost of South Africa has a three-shot lead after three rounds of the Buick Classic, but U.S. Open winner Tom Kite is in contention at Harrison, N.Y.

Kite shot a four-under-par 67 Saturday at the Westchester Country Club to put himself in position to join Hale Irwin and Billy Andrade as Buick winners scoring a second consecutive victory.

Irwin won the 1990 Buick immediately after the U.S. Open, and Andrade won the Kemper Open and the Buick title on consecutive weeks last year.

Frost, who has led or shared the top spot all the way in this $1-million event, pulled away with a 67 for a 202 total, 11 under par.

Duffy Waldorf was next at 205 after a 69, and he was followed by Jeff Maggert at 206 after a 66.

Bill Britton (69) and Fred Funk (71) were tied with Kite at 207, six under par.

Gibby Gilbert followed a course-record 62 with a five-under-par 65, taking a six-shot lead over defending champion Jim Colbert in the $450,000 Southwestern Bell Classic at Kansas City, Mo.

Gilbert, who has recorded 14 birdies and one bogey on the 6,496-yard Loch Lloyd Course, tied the Senior PGA Tour record with a 36-hole total of 127.

Colbert, a Kansas City native and crowd favorite, shot a 66 and was in second place at 133, one stroke better than Kermit Zarley (66) and Dick Hendrickson (68).

Gilbert, 51, has not won a tournament since he and former touring pro Grier Jones, a longtime friend caddying for him this week, took the World Team Championship in 1977.

“It’s my tournament to win or lose now,” Gilbert said. “If I don’t win, shame on me.”

Patty Sheehan’s tournament-record 63 gave her a nine-stroke lead through three rounds of the LPGA Rochester International at Pittsford, N.Y.

Sheehan birdied nine holes and had no bogeys to finish a stroke better than the single-round record she shared with Alice Ritzman and Dale Eggeling. The nine-under 63 also tied the best round of Sheehan’s career.

Sheehan’s 54-hole score of 18-under 198--nine strokes ahead of second-place Michelle McGann--also beat the previous three-round tournament record by four strokes.

McGann, three strokes ahead of Jane Crafter, Dawn Coe and Nancy Lopez, all but conceded the $60,000 first prize to Sheehan, who needs four more victories for 30, which would qualify her for automatic induction into the LPGA’s Hall of Fame.
