Phil Mickelson has withdrawn from this week's WGC-Cadillac Match Play Championship.
According to Golf Channel, Mickelson told the PGA Tour on Sunday that he won't play at TPC Harding Park in San Francisco because of "personal reasons."
Mickelson, the No. 18 player in the world, has skipped the match-play event since 2011 because the old February date conflicted with school breaks for his kids and the former venue, Dove Mountain, was not a favorite of his. Both of those factors changed this year, and Mickelson had given every indication he intended to play.
Mikko Illonen, the No. 68 player in the world, will take Mickelson's spot. Tim Clark (injury) and Luke Donald (wedding) had already pulled out from the event.
The five-time major champion is still committed to The Players and the Wells Fargo Championship, the two events played directly after the Match Play.
