FORT WORTH, Texas — Charlie Wi made a 32-foot birdie putt on the par-3 16th hole soon after a weather delay at Colonial, taking the lead after playing partner David Toms blew a seven-stroke advantage in the third round Saturday.
After Wi holed the birdie putt, Toms' 16-foot par chance just missed for a two-stroke swing.
Wi finished with a 4-under 66 to get to 13 under, a stroke better than Toms (74) and four ahead of John Senden (70).
"I didn't think I'd be able to close the gap like I did," said Wi, who began the round just hoping to get within three or four strokes.
Toms built his huge lead with bogey-free 62s in the first two rounds. He opened with a birdie Saturday before three bogeys in a five-hole stretch while Wi got started with consecutive birdies.
Even worse for Toms was a three-putt from 7½ feet for double bogey at No. 14, where Wi chipped to 12 feet to save par right before a 1-hour, 20-minute delay.
Wi made his 100th cut in 147 PGA Tour events this weekend, but the 39-year-old South Korean has never won.
The 44-year-old Toms is a 12-time winner, but is looking for his first victory in more than five years. He is coming off a playoff loss to K.J. Choi last weekend at The Players Championship.
While Toms now has another disappointment to overcome, at least he still has one more round to play at Hogan's Alley.
Stuart Appleby (67), Paul Goydos (67) and Mark Wilson (71) were 8 under.
After blasting out of a frontside bunker at the par-4 14th, Toms three-putted for his first double bogey in a stretch of 343 holes at Colonial. That coupled with Wi's impressive up-and-down at the same hole cut the gap to one stroke.
"Until then, I wasn't even thinking about the lead," Wi said.
Before Toms and Wi finished No. 15, play was stopped because of an approaching storm. Only a little bit of rain fell before play resumed and both made their par putts.
Wi's tee shot at No. 16 landed on the back side of the green. Toms pushed his right into the rough.
Toms got to 17 under with his opening birdie Saturday at the 565-yard No. 1 hole, chipping from just short of the green to 6 feet. Then came three bogeys in a five-hole stretch when he had a couple of bad bounces.
His approach at the par-4 second hit on the front of the green but rolled back into the greenside bunker. He blasted to about 19 feet and two-putted for his first bogey in 38 holes.
After missing the fairway left at No. 3 and hitting a low liner approach that stopped just short of the green, Toms pushed a 5½-foot par chance just right of the hole.
At the difficult 247-yard fourth hole, his tee shot landed in the frontside bunker so deep that the 5-foot-10 Toms' head was barely visible from the back of the green when he blasted to 9 feet. When he made that putt, he had a slight fist pump that was more relief than celebration.
But Toms got another bad break when his approach at No. 6 rolled off the right side of the green. He chipped 9 feet past the hole and couldn't save the par, and walked away with holding both hands out.
After carding 31s on both nines on each of the first two rounds, Toms finished the front side Saturday at 2-over 37. He had already missed five greens, matching his total for first two rounds.
Still, at that point, Toms still was 14 under with a three-stroke lead over Wi and Wilson, playing in the group ahead.
"I felt after the first six holes, I was just hanging on. ... Trying not to make a mistake," Toms said. "Maybe I'll go out there with a little pressure off of me and see if we can do better (Sunday)."
