Phil Mickelson carded a bogey-free six-under-par 66 to take the lead after the second round of the Ford Championship in Florida.
Mickelson finished the day at 14 under on 130 – two strokes clear of Billy Andrade who shot a 66.
Jose Maria Olazabal carded a 69 to finish three behind on another day of low scoring on Doral Resort’s Blue Monster, with Billy Mayfair a further shot back.
Vijay Singh (67), Tiger Woods (70), defending champion Craig Parry (66), last week’s match-play champion David Toms (66), James Driscoll, Tim Clark, Stewart Cink, Hunter Mahan, Joey Snyder III, Britain’s Brian Davis and Franklin Langham are all five strokes behind.
Mickelson has already has won twice on Tour year and is a cumulative 71 under par in stroke play and has also led his past nine stroke-play rounds.
“I didn’t necessarily hit the ball as well as yesterday, but I was able to salvage a lot of pars with my short game and that led to a bogey-free round,” said Mickelson, who missed half the fairways.
“There are so many good players right there I’ve got to go out and keep pushing to make birdies.”
Singh and Woods, who rank 1-2 in the world, were not totally satisfied with their second rounds.
“I’m really happy with the way I’m striking the ball,” Singh said. “It was the easiest five-under I could have shot. I left a lot out there, but you just have to take what you get.”
Woods found only five fairways for the second successive day but this time it cost him as he ran up four bogeys, including three in a row.
“My bogeys were caused by a couple of three-putts, and on top of that some poor decisions in commitment to the greens,” said Woods, whose streak of holes without dropping a shot here ended at 62.
A total of 83 players made the cut, which fell at three under on 141.
But the later players certainly had it easier, with the four leaders all playing in the afternoon.
