Marana, AZ (Sports Network) - Rory McIlroy and Tiger Woods, the top-2 ranked players in the world, both lost in their first-round matches Thursday at the World Golf Championship - Accenture Match Play Championship.
McIlroy lost to Shane Lowry, 1-down. McIlory and Lowry have played together for years in Ireland. Charles Howell, one of Woods' closest friends, took down Woods, 2 & 1.
Macon's Russell Henley pulled an upset of his own knocking out Charl Schwartzel 1-up in his match.
There were two matches left on the course as play was suspended Thursday evening. Carl Pettersson was 1-up on Rickie Fowler as they played the 18th hole. The winner of that will next face Lowry. Francesco Molinari and Gonzalo Fernandez-Castano were all square through 15 holes. That winner gets Howell in round two.
Those two matches will conclude on Friday morning before the second round gets underway at The Golf Club at Dove Mountain.
Snow halted play on Wednesday and the start of Thursday's action was delayed until 3 p.m. (ET) while the players waited for the snow to melt.
The other two top seeds - Luke Donald and Louis Oosthuizen -- both escaped tough matches. Donald fended off Marcel Siem, 1-up, and Oosthuizen took down Richie Ramsay, 2 & 1.
