LA JOLLA (California): World number one Tiger Woods was one-under-par for his opening nine holes of 2003 when bad weather ended play for the day at the US$4.5 million Buick Invitational on Thursday.
Woods, who had surgery to remove fluid around his anterior cruciate ligament in his knee in December, teed off four hours late at a wet Torrey Pines North course after fog had twice disrupted play in the first round.
The 27-year-old American last played a competitive round in early December and his first tee shot on Thursday went straight into the crowd.
Woods's recovery on the 520-yard par-five first was a sliced three-wood into the thick rough surrounding the green. But after a wedge and two putts he walked away with a par.
He again drove into the rough at the second and had to settle for another par.
Woods bogeyed the fourth before bouncing back in style with birdies at the fifth and eighth.
Rain then started to fall and play was called off for the day after he reached the turn at one-under-par.
Early leader PGA Tour rookie Arron Oberholser was on his way to his best score as a professional during the first day.
Oberholser, 28, carded six birdies and no bogeys in 16 holes on the par-72 Torrey Pines North course. – Reuters
