Mickelson focused on Firestone
Phil Mickelson is focused on performing well at the WGC-Bridgestone Invitational this weekend, rather than usurping Tiger Woods at the top of the world rankings.
The 40-year-old left-hander was on course to wrest the world number one ranking from Woods after moving one shot behind halfway leader Retief Goosen at Firestone Country Club in Akron, Ohio.
