Tiger Woods, chasing his first victory in two years, made his lone bogey of the day at the final hole to finish two strokes behind third round leader Jason Gore at the Wyndham Championship.
A stiff and sore Woods, the overnight co-leader, arrived at Sedgefield Country Club about three hours before his round to receive treatment on an undisclosed ailment.
Once he got onto the course he had superb control of his driver on the few occasions he used it, and even better mastery of his putter, holing a series of clutch par-saving putts throughout the day, but only three birdies.
"It was a grind today," Woods, who is in a three-way tie for second, told reporters.
"Like yesterday, I kept leaving myself in tough spots above the hole and had to putt too defensively because of it. Consequently I didn't make a bunch of birdies."
With a chance to join boyhood friend Gore in Sunday's final grouping, Woods's downhill, six-foot par putt lipped out at the par-four 18th, much to the disappointment of the huge gallery that followed him every step of the way.
The three-putt bogey, which capped a two-under-par 68, dropped Woods into a tie with fellow American Scott Brown (66) and Swede Jonas Blixt (62).
American Gore, who has known Woods most of his life, mixed nine birdies with one bogey for a 62 to vault into the lead at 15-under 195.
