Tiger Woods and most of the world's best golfers were on their games Thursday in the Cadillac Championship.

Except for the world's No. 1 player.

Woods made birdie on half his holes on the Blue Monster at Doral for a 6-under 66. He was part of a five-way tie for the lead that included Masters champion Bubba Watson, former U.S. Open champion Graeme McDowell, Sergio Garcia and Freddie Jacobson. Phil Mickelson, Steve Stricker and Hunter Mahan were among those one shot behind.

It was another struggle for Rory McIlroy. He hit only three fairways and made six bogeys that kept him at par or worse on a perfect day for scoring. He wound up with a 73, and has yet to have a round under par this year.
