Furyk is chasing his first win since 2007
American Jim Furyk took advantage of a lacklustre day from Padraig Harrington to take the lead after the third round of the Transitions Championship.
Furyk fired a four-under 67 to edge to 11 under and lead by three from KJ Choi, Retief Goosen, Bubba Watson and Carl Pettersson in Florida.
Overnight leader Harrington carded a one-over 72 to slip to seven under alongside Luke Donald and Jeff Maggert.
England's Justin Rose was in a group tied for 14th on five under par.
The 39-year-old Furyk, the 2003 US Open champion, opened with a birdied and picked up three shots coming home as Harrington mixed two birdies with three bogeys after shooting 65 on Friday.
South Korea's Choi also hit 67, while South Africa's Goosen, big-hitting American Watson and Sweden's Pettersson also took 70 and England's Donald climbed into a tie for sixth with a 67.
Furyk has not won since the Canadian Open in 2007, a span of 58 tournaments. It has also been nearly three years since he last held the 54-hole lead on the PGA Tour.
"I want to go out and win a golf tournament," said the 13-times PGA Tour winner.
"That's what we play golf for. That's what I practise hard for, and I haven't been able to do that in over two-and-a-half years.
"I was real happy with the back nine. I felt like I played solid on the front," he said. "I was happy with the way I controlled the golf ball. I knocked in some putts, which helps.
"It was just fun to see some putts go in. The difference in the back nine and the front nine was I saw a few more putts go in on the back side."
He also had some good fortune, and at the 16th a poor tee shot hit a tree and bounced back onto the fairway instead of going in the water.
Harrington, after seven birdies in round two, had only two on Saturday, one at the opening hole the par-five and another at the 16th, but a bogey five at the last summed up a disappointing round.
He remained optimistic but admitted: "I don't want to give Jim a four-shot lead over a four-round tournament, let alone one round.
"There's enough guys behind that somebody is going to shoot a good score and put some pressure on him. Hopefully it's me."
