Webb Simpson is in cruise control atop the leaderboard midway through the third round of the Players Championship.
Simpson started moving day at TPC Sawgrass with a five-shot lead and has increased his buffer zone to six shots having just entered the back nine on Saturday.
At 17-under-par, former US Open winner Simpson has Greg Norman's 54-hole score record of 19 under in his sights.
Simpson leads New Zealander Danny Lee (10 holes) who is at 11 under, while Australia's Jason Day (through 12 holes) is a shot back.
World No.1 Dustin Johnson headlines a share of fifth at nine under.
Marc Leishman is next best of the Australians at seven under having posted a 67, while countryman Adam Scott has dropped a shot through 15 holes to fall to six under.
Earlier, Tiger Woods emerged from the wilderness to rocket up the leaderboard.
Woods, a two-time Players winner, started the day a whopping 14 shots off the pace.
But 14-time major champion Woods clawed his way back into contention with a sizzling 65 - his best score at golf's unofficial fifth major.
He shares ninth at eight under alongside Jordan Spieth (65).
Woods had the enormous galleries on the edge of their seats with a bogey-free front nine of six under 30.
It was one shot worse than the front nine record of 29, set by Martin Kaymer in 2014.
The 42-year-old Woods then jagged birdies at the 11th and 12th but that was it for his charge, with a bogey at the 14th.
