THOUSAND OAKS, Calif. (AP) _ Tiger Woods' end-of-the-year tournament that pays $1 million to the winner has been increased to include 18 players because a World Golf Championship event was canceled.

The Williams World Challenge, to be played Dec. 13-16 at Sherwood Country Club, was supposed to feature the top 12 players available from the world ranking and four other players chosen by the Tiger Woods Foundation.

The cutoff for the ranking was Oct. 1.

Organizers decided to extend the deadline by one week because the American Express Championship in St. Louis was canceled the day after the Sept. 11 terrorist attacks.

Some players who qualified Oct. 1 were no longer on the list a week later.

``We felt the most equitable thing to do was to apply both lists and select the players accordingly,'' tournament director Greg McLaughlin said.

The expanded field allows Scott Hoch to make his debut in the $4.1 million event that will feature players from 10 countries.

Davis Love III will defend his title against a field that includes the four major championship winners _ Woods, Retief Goosen, David Duval and David Toms.

The rest of the field includes Vijay Singh, Darren Clarke, Colin Montgomerie, Bernhard Langer, Jim Furyk, Scott Verplank, Padraig Harrington, Thomas Bjorn, Lee Westwood, Jesper Parnevik, Fred Couples and Mark O'Meara.

The Williams World Challenge had 12-man field the past two years.
