SAN DIEGO (AP) - As many times as Tiger Woods has played and won at Torrey Pines, he has never figured out the patchwork shades of blue in the Pacific Ocean below the cliffside course. Looking out from the fourth green Wednesday morning, his New Zealand caddie told him the darker the shade, the colder the water.

It was a fitting start to his 2007 season, staring at segments that represent old and new, but blending.

The Buick Invitational is his first tournament of the season, but Woods carries over from last year a PGA Tour winning streak that dates to July. He is going for his seventh in a row on the PGA Tour, and odds are in his favor as the two-time defending champion.
