Even with a costly bogey on the difficult 18th hole, Puyallup's Ryan Moore shot a 5-under-par 65, and appears headed to a sudden-death playoff at the PGA Tour's Wyndham Championship in Greensboro, N.C.

Moore, Jason Bohn (62) and Kevin Stadler (66) are all in the clubhouse tied at 16-under 264.

The Cascade Christian graduate and former four-time All-American at UNLV led for a brief moment when he knocked in a 4-foot birdie putt on the par-3 16th. He was caught by Stadler.

And on the 504-yard, par-4 18th at Sedgefield Country Club, playing as the most difficult hole all week, Moore narrowly avoided the cart path, and drove into a thick patch of rough on the right side.

He tried to muscle out a 5-iron from 206 yards out, and hit more grass than ball. The ball came out fat, and landed in a sand bunker short of the green.

His 9-iron third shot from 51 yards away landed close, but Moore's 8-foot par-saving putt up the hill slid by on the left.

"Just lost the speed," Moore told CBS Sports after his round. "These greens have really quickened up … but they haven't been quick all week."

Standing on the 18th tee with a one-stroke lead, Stadler, too, hit his drive into the right rough. He had to hit a wedge out, and his third shot from 144 yards out hit a slope on the left side, and trickled back toward the hole.

Facing an 8-foot par putt to win the tournament, Stadler's putt also lost speed and missed on the low side.

This is the second consecutive season Moore has been in a playoff. He lost to Adam Scott in the 2008 Byron Nelson Championship last April.
