Just when it looked like opening day of the PGA Tour's first full-field event would be a lot like opening day of the PGA Tour season last week, Shigeki Maruyama blew into first place at the Sony Open in Hawai'i with a huge grin yesterday.

Sony started with rain, rainbows and weird winds gusting up to 30 mph at Waialae Country Club — and predictions of worse to come. PGA official Mark Russell said gusts up to 55 mph are predicted this afternoon, but the tour is planning to play unless conditions are unsafe or unplayable, such as balls blowing off the greens or tees.

"We'll just come in and see. Hopefully it won't be that bad É," Russell said. "If we can play, we certainly will. We'll take every precaution we can."

In the midst of the weather madness, Maruyama shot a 5-under-par 65, easing into first alone when he hit his tee shot within six feet on the 17th and buried his sixth birdie putt. Maruyama, playing on a sponsor's exemption after an awful 2008, is one shot ahead of five golfers including Geoff Ogilvy, who won last week's Mercedes-Benz Championship by a bunch.

Maruyama, 39, became the second Japanese golfer to win on the PGA Tour — after Isao Aoki, who won here in 1983 — when he captured the 2001 Greater Milwaukee Open. He held the lead here after the second and third rounds in 2006. But last year, his 25th-place finish at Sony was his best in 18 starts, sending him home in September to work on his golf and his psyche.

"It's not like my driver was bad or my putting was bad," Maruyama said through an interpreter. "It's been the whole, entire thing, all of my game. But I made some progress and I feel like I've come about 70 percent of the way that I really need to."

Maruyama found his "Smiling Assasin" attitude back home and played well enough in nine Japan tour starts to finish 36th on the money list — he was 207th here. Yesterday, he one-putted 10 greens to ease past Ogilvy, Boo Weekly, Brian Gay, rookie Webb Simpson and Nathan Green.

Ogilvy won by six shots last week on Maui. He has shaved his beard since, but little else has changed. He didn't miss a beat yesterday and playing partner Weekley stayed right with him. Both shot 4-under-par 66 in the morning, along with Gay and Simpson, after "saying a quick prayer" before his first drive. Maruyama and Green worked their way to the top while rain blew through Waialae.

Ogilvy had only one bogey the first three rounds last week at Kapalua Plantation. He had two yesterday, but fired back with six birdies — chipping in on his opening hole — on a course where he has one Top-10 finish (in 2007) and four missed cuts.

"Right now he's feeling the magic," Weekley said. "He's feeling his swing, what he's doing. If I can just hang with him I might have a chance."

Ogilvy called the course "tricky but do-able" and said he has a little carryover from Mercedes, along with an extra week to get comfortable with the wind and whatever else Hawai'i throws at golfers. Playing with Weekly and Kenny Perry (69) also helped.

"Boo is always fun to play with and Kenny is one of the nicest guys in the world," Ogilvy said. "So it was a nice group and nice that we all had a good one."

Two Hawai'i teenagers are not far back.

Moanalua High School senior Tadd Fujikawa, who turned pro two years ago after finishing 20th here, double-bogeyed the first hole and fought back to shoot a 71. He is tied for 51st.

'Iolani freshman Lorens Chan, 14 and the only amateur, shot 72 and shares 79th with, among others, Ernie Els. It was the two-time Sony champion's worst score here in his 21 rounds, and only his third score in the 70s.

The top 70 and ties advance after the second round.

With the wind blowing hard from the southwest direction, when it wasn't swirling, Waialae's par-70 layout — even with tees moved up to compensate for the breeze — played to an average score of 71.326. The par-4 first hole was particularly devastating, playing tougher than the par-5 ninth (4.646 to 4.160). Fujikawa was in good company, with 13 others taking double, including Notah Begay and John Huston, who won the 1998 Hawaiian Open here by shredding Waialae with a then-record 28-under.

Huston's worst round that year was 66. He had that many yesterday midway through his 15th hole and withdrew with an arm injury after shooting a 79. Darron Stiles withdrew for personal reasons after a 78.

Charles Howell, who was second here two years ago, is two shots behind Maruyama along with 2001 champion Jerry Kelly and Luke Donald, making his first start since wrist surgery in August. Defending champion K.J. Choi shot 68, as did 2000 champion Paul Azinger.

Chad Campbell flew to Hawai'i from Dallas Saturday, intending to play the Sony, where he finished second in 2006. But, Campbell had forgotten to sign up for the tournament and the deadline was Friday. He played a round of golf — not at Waialae — and flew home.

"It's one of my top five favorite tournaments we play all year," Campbell told the Associated Press. "It's one of my favorite golf courses. That's what (stinks) more than anything."
