KAPALUA, Maui — Geoff Ogilvy opened the U.S. PGA Tour season with a bogey-free 6-under 67 and a one-shot lead in the Mercedes-Benz Championship today, a score that surprised him only because of the location.

"I haven't shot very many good rounds around this course, so maybe that's a surprising thing," said Ogilvy, who had not broken 72 in his previous two trips to the winners-only tournament. "But the fact that I'm playing OK is not surprising."

Ogilvy won the Australian PGA Championship and tied for sixth in the Australian Open, and he was just as crisp with his game in taking the first-round lead over Ernie Els, Kenny Perry and fast-closing Johnson Wagner.

With only moderate wind on a Plantation course that Ogilvy refers to as "extreme golf," eight players broke 70 and 20 players in the 33-man field broke par.

FedEx Cup champion Vijay Singh, who will have knee surgery next week, was not among them. He made double bogey on the opening hole and rallied for a 73. Defending champion Daniel Chopra was headed for a round in the 80s until he birdied the last two holes for a 79.

That Ogilvy was atop the leaderboard was surprising only because his average score in eight previous rounds was 73.875. But he kept practicing during his brief respite at home in Arizona, and it showed.

"We only finished the Australian Open three week ago," Ogilvy said. "And three weeks isn't enough to get rusty."

Els arrived in Maui having played only once in the last six weeks, and that worked well for him. In his first visit to Kapalua in four years, he made only one blunder — a tee shot into the hazard on the par-5 15th — to get his season off to a solid start.

Wagner, one of a dozen newcomers to the winners-only Mercedes with his victory in the Shell Houston Open, wasn't even in the picture until a birdie-birdie-eagle finish. Perry joined the group at 68 with a birdie on the last hole.

Davis Love III, who won the final event of 2008 at Disney World, and Ryuji Imada were in the group at 69. Imada ran off seven straight birdies starting at No. 6 — one short of the U.S. tour record — but followed that streak with consecutive bogeys.

As for all the hype over the youngsters?

Anthony Kim had a 71, while Camilo Villegas had to rally for a 74.

It was a typical idyllic start, with moderate wind, occasional light showers, sunshine, rainbows and plenty of optimism about the new season.

"I want to have a good season, like everybody," Els said.

The Big Easy was off to a phenomenal start with an eagle on the par-5 fifth hole and a 31 on the front nine. He was 6 under through 11 holes, but played the rest of the way at 1 over — despite playing two par 5s — and had to settle for a 68.

"I would have taken it before I teed off," Els said. "But I'm a little hot under the collar right now."

He hooked his tee shot into the hazard on the 15th, had to take a penalty drop and hit out sideways, and he did well to make bogey. Els had a 4-iron into the green on the par-5 18th, but left it out to the right to avoid trouble on the left, and missed a 10-foot birdie.

Ogilvy also finished with a par, but was all smiles.

He was rarely in trouble, and the only time he had to get up-and-down was on the par 5s. But with a 3-iron to the 18th green, he pulled it into the hazard, and after a lengthy discussion where to drop, he was faced with a 50-yard pitch, which he hit to 4 feet for par.

Hall of Fame quarterback John Elway hit the ceremonial tee shot to begin the season, a 350-yard drive that speaks to the elevation, wind and the grain in the grass that makes the Plantation course unlike any other they will play all year.

Wagner is among a dozen newcomers to Kapalua, but he arrived last Friday and quickly became acquainted.

"I've played Saturday and Sunday, every day I've been here, and fell in love with the golf course," Wagner said. "It's early, but I feel really comfortable out here."

He didn't look terribly comfortable on the greens, which can takes years of experience to figure out the slope and grain. But it all came together at the end, with a 10-foot birdie down the slope on the 16th, a 25-foot birdie across the grain on the 17th and his 18-foot eagle on the final hole.

"It was a great finish, and turned a 71 into 68 real quick," Wagner said.
