Tiger Woods said he has assembled "an amazing field" for the 15th version of his charity golf tournament that starts Thursday in Thousand Oaks.
Woods and 17 other players will compete in the Northwestern Mutual World Challenge, a four-round event at Sherwood Country Club that pays $1 million to the winner.
Woods, 37, is a five-time winner of the unofficial event, which next year is moving to Florida.
"I feel very comfortable," Woods said Wednesday after playing in the pro-am.
Coming off a three-week respite from competitive play, "I haven't really done a whole lot golf-wise but I've been training quite a bit," said Woods, the PGA Tour player of the year. "I was very pleased with the way I was able to play today."
The other players are defending World Challenge winner Graeme McDowell, former event winner Jim Furyk, Rory McIlroy, Bubba Watson, Lee Westwood, Ian Poulter, Jason Dufner, Matt Kuchar, Hunter Mahan, Jason Day, Jordan Spieth, Dustin Johnson, Zach Johnson, Steve Stricker, Bill Haas, Keegan Bradley and Webb Simpson.
Woods said the tournament was moving to Florida partly because so many PGA players live there, but that it "wasn't an easy decision" to move because Sherwood Country Club "has been fantastic over the years."
