Mark O'Meara, who shot 19-under par while winning last weekend, continues the hottest hand in golf.

"My kind of game is one that can just click on, boom, and all of a sudden I start to stiff it," O'Meara said yesterday after a 5-under-par 67 maintained his one-stroke lead after three rounds of the 90-hole, $1.3 million Las Vegas Invitational.

He clicked on at the Desert Inn, with birdies on five of six holes. He completed one round over each of three desert resort courses in 198, 18-under-par. "Now," he said, "it gets down to the nitty-gritty."

The final two rounds will be at Las Vegas Country Club, easiest of the three courses used for the first 54 holes. "And there's still a lot of guys left in contention," O'Meara said.

Chief among them are Bob Tway and John Cook. Tway scored an eagle-3 in his 65 at the Desert Inn and was one stroke back. Cook, who had a third-round 66 at Spanish Trails, was another stroke back at 200.

Emlyn Abrey (68, Spanish Trails) is fourth at 202. Canadian Richard Zokol (66, Desert Inn) is next at 203. Loren Roberts (70, Desert Inn) and Phil Blackmar (68, Spanish Trails) follow at 204.

LPGA: Cathy Gerring shot a second straight 69 and leads after two rounds of the World Championship in Cely, France, while Japan's Ayako Okamoto surged into contention with a six-under-par 66, the best round of the tournament on a new 6,155-yard, par-72 course.

Gerring, one of 13 U.S. golfers in the 16-woman field, is at 138, six-under-par and one stroke ahead of Okamoto. Americans, Betsy King (69) and Danielle Ammaccapane (70), are tied for third at 141. Okamoto had five birdies, one bogey and an eagle at the 10th, where she chipped in from 10 yards.

First-round co-leader Cindy Rarick dropped to sixth at 74 -- 143. Beth Daniel was tied for seventh at 74 -- 145.

Seniors: Bruce Crampton and Robert Gaona each birdied the final hole to tie Bob Betley at five-under par 67 for the first-round lead at the Gatlin Brothers Southwest Classic in Abilene, Tex.

Al Kelley, Terry Dill and J.C. Goosie are one shot back on the par-72, 6,843-yard Fairway Oaks Country Club course. Jack Fleck, John Paul Cain, Ben Smith, Don January and Rives McBee are two back at 69.
