Woods rues putts despite solid start

Woods was three under par after the first round in San Diego but that left him five shots behind South Korean rookie Sunghoon Kang.

"I could have been a lot better if I took care of the par fives a little bit more," said world number three Woods.

"I didn't leave myself any putts. I kept leaving myself above the hole. And I didn't take advantage of the par fives."

Rookie Kang finished with back-to-back birdies for a round of eight under, and his 64 total gave him a one-shot lead over Alex Prugh and Rickie Fowler, with another rookie, Chris Kirk, a shot further back.

Phil Mickelson and John Daly both hit 67 on the tougher South Course, Daly played the venue which saw his last win when he took the honours in the same tournament in 2004.

Daly said: "This place means a lot. The top golfers play here every year. That says something."

Daly last year missed the cut at the course and his comments then, after rounds of 79 and 71, led to speculation that he was ready to retire from the game.

Kang said: "I tried to keep to the fairways and it worked really well. I really had a good chance on the par fives. That's why I played very well today."

England's Justin Rose shot a 72, while fellow Europeans Alex Cejka and Jesper Parnevik shot 74 and 75 respectively.
