Play was pushed back twice on Thursday as the grounds crew at La Costa scurried to try and make the course playable. There were large streams running through some fairways and large collections of water in several bunkers.
'Quite simply, the golf course is unplayable,' said Mike Shea, Senior Director of Rules for the PGA Tour. 'The greens are fine but there is a lot of water in the bunkers which still require quite a bit of work. The main concern is the amount of casual water in the fairways, caused by the creek which runs through the center of the course overflowing.
'We just could not play the game properly because of the condition of these fairways.'
The plan is to begin the second-round matches at 10:00 a.m. ET Friday morning off the first and 10th tees. The third-round matches are scheduled to begin around 2:45 p.m. Friday with all matches going off No. 1.
Play was supposed to begin at 12:15 p.m. Thursday but thanks to nearly two inches of rain that pounded La Costa Wednesday night and Thursday morning, the start time was pushed back to 2:30.
When officials could not get the course in shape by then, play was delayed until 3:50, and ultimately called for the day. The grounds crew will be working hard the remainder of Thursday in an effort to get La Costa in the best condition for Friday's marathon session.
'The forecast is good, however,' said Shea. 'We look like we will have a sunny afternoon and although there are a few showers forecast for the remainder of the week, they are nothing compared to what we had overnight.'
Tiger Woods, the No. 1 seed in the Bobby Jones bracket and the defending champion, needed a birdie at 18 and a few mistakes down the stretch by John Rollins to win his first-round match, 1-up. Woods will face South Africa's Trevor Immelman in the second round.
All of the remaining No. 1 seeds advanced to the second round.
Vijay Singh, the top seed in the Gary Player bracket, trounced Shingo Katayama, 5 and 3. Mike Weir, last week's Nissan Open champion and No. 1 seed in the Ben Hogan bracket, beat 2002 PGA Champion Rich Beem, 3 and 2, and Davis Love III, tops in the Sam Snead bracket, defeated Briny Baird, 2-up.
Of all the No. 1 seeds, Love has the most intriguing match in the second round. He will battle good friend Fred Couples, while Singh meets Jerry Kelly and Weir takes on Stephen Leaney.
Phil Mickelson was a winner in Wednesday's first round as he bested England's Lee Westwood, 3 and 1.
The biggest upset in Wednesday's first round involved Retief Goosen, the No. 2 seed on the Hogan side. He was defeated by John Huston, 2 and 1, and was the highest seed eliminated in the first round.
Both of last year's stunning major winners advanced on Wednesday. British Open winner Ben Curtis defeated Charles Howell III, 2-up, and PGA Champion Shaun Micheel needed 21 holes to oust Englishman Paul Casey, 1-up.
