Miami, March 16:

Phil Mickelson won the WGC-CA Championship edging fellow American Nick Watney by one stroke on Sunday. Mickelson claimed his first win in a World Golf Championships event, shooting 69 to finish at 19-under-par 269.

Mickelson and Watney started the final round tied for the lead and Mickelson took the lead for good when Watney bogeyed the 11th hole. They both made a mess of the par-five 12th with

bogeys, and then matched each other with pars over the final six holes. Watney shot 70 for 18-under, while compatriot Jim Furyk (67) stormed home for third place on 16-under, with Tiger Woods equal ninth on 11-under.
