Tiger challenges for world crown

Tiger Woods made a strong start to his bid for a fifth Chevron World Challenge title in California yesterday. An opening round of 69 moved the former world No 1 into a share of second place in the 18-player field, alongside his fellow American Steve Stricker.

But while Woods and Stricker had good cause to be satisfied with their rounds, KJ Choi almost made them look like first-day slouches as he carded a 66 to open a three-shot lead.
