(CNN) -- Nick Watney holds a three-shot lead going into the final round of the PGA Championship after carding a blistering six-under 66 at Whistling Straits.
Watney's nearest challengers are Rory McIlroy of Northern Ireland and fellow American Dustin Johnson, who both carded 67s Saturday.
China's Liang Wen-chong also charged into contention with a course record with 64 - carding eight birdies to tie for fourth on nine-under with Australian Jason Day (66) and German Martin Kaymer (67).
Steve Elkington (67), Zach Johnson (69), Jason Dufner (69) and Jim Furyk (70) are at eight-under 208, but Tiger Woods carded an even-par 72 and is 10 shots back on three-under.
After the fog and delays of the first two days, Saturday had the field play catch up and a number of star names were halfway casualties, including defending champion YE Yang.
Three-time major winner Ireland's Padraig Harrington and reigning British Open champion Louis Oosthuizen of South Africa also missed the cut.
The scene is set for a thrilling final round Sunday with seven of the top 10 players seeking their first major title, including Watney
Seven of the top 10 players on the leaderboard are seeking their first major championship, including Watney and the exciting young McIlroy, who led the British Open at St.Andrews before falling away in his second round.
"I am going to go out there tomorrow, put a tee in the ground on No. 1 and just focus on that shot," Watney told the official PGA website.
"It is going to be a long day and a tough day but I am really looking forward to it."
McIlroy, who shot a final round 62 to win his maiden PGA Tour title earlier this year at Quail Hollow, finished tied third in last year's PGA Championship and gave an assured performance.
"I didn't do a lot wrong. I saved pars when I needed to and took advantage of the holes where I gave myself good chances for birdies," he said.
Woods, who had the rough end of the weather conditions and delays, saw his hopes all but disappear with three bogeys on the front nine of his third round.
"Unfortunately you have to make birdies on the par-fives and I haven't done that," Woods said.
The world number one will be hoping to finish in the top 15 of the final major of the season to boost his bid to gain an automatic spot for the U.S. Ryder Cup team.
