BELEK, Turkey (AP) -- Rory McIlroy and Tiger Woods have lost their opening matches at the eight-player World Golf Finals.
McIlroy lost to Matt Kuchar by six shots Tuesday and Woods fell to Charl Schwartzel by one shot in the $5.2 million event at the Sultan course in Antalya.
In the other group of the medal match-play format, Lee Westwood beat Webb Simpson by one shot and Justin Rose defeated Hunter Mahan by four strokes.
Woods and McIlroy play each other Wednesday in the last of their three group matches, but both could already be eliminated by then. The top two in each group advance to the semifinals.
The event is sponsored by Turkish Airways, with the winner to receive $1.5 million.
