Miami - Britain's Tommy Fleetwood birdied four of the last six holes, including two spectacular birdie putts from beyond 40 feet, to grab a one-stroke lead after Saturday's third round of the PGA Tour's Honda Classic.
The 29-year-old Englishman, runner-up at the 2018 US Open and 2019 British Open, fired a three-under par 67 to finish on five-under 205 after 54 holes at PGA National in Palm Beach Gardens, Florida.
Fleetwood, who began the day three strokes off the lead, made six birdies against three bogeys on a wild day where he was the only player to shoot a round under par in the final eight groups.
"It's funny, really, how tough certain shots can play," Fleetwood said.
"There are just so many factors on a golf course. You can only hit golf shots and see where they play."
American Brendan Steele, the 36-hole leader who was three ahead of Fleetwood when the day began, fired a 71 to stand second on 206 with England's 46-year-old Lee Westwood and 42-year-old Luke Donald both on 207 after 71s on Saturday.
"I didn't have my A-game today," said Westwood, seeking his first PGA win since 2010.
"Struggled with my game a little bit. Stayed patient and ground it out. I don't think I did too much damage."
Fleetwood dropped the ball within six feet at the par-3 sixth and made the birdie putt, then suffered a three-putt bogey from 85 feet at the par-3 seventh. He answered with a five-foot birdie at the ninth but needed four shots to find the 10th green and took a bogey.
His closing charge began with a "lovey putt" for birdie from 14 feet at 13, followed by a monster 45-footer for birdie at 14.
"Just looking to lag that one up close. Wasn't expecting it to go in," Fleetwood said.
"Bit of a bonus there."
After finding sand with his first two shots at the par-3 15th, Fleetwood blasted out and sank a testy 10-foot bogey putt.
"The putt at 15 for bogey was big," Fleetwood said.
It bolstered his confidence heading to the finish and at the par-3 17th he rolled in a 48-foot birdie putt.
"At 17, again, another bonus one in there, just to walk it in," Fleetwood said.
On the par-5 18th, Fleetwood became only the day's seventh player to reach the green in two, then rolled a 44-foot eagle putt to two feet and tapped in for birdie.
Fleetwood, a five-time European Tour winner who is seeking his first PGA title, has his first 54-hole lead on the US tour.
Steele birdied two of the first three holes but back-to-back bogeys at four and five and again at 10 and 11 were more than a 12-foot birdie putt at 17 could offset.
Westwood made three bogeys and two birdies in the first seven holes, then grinded out back nine pars with a birdie at 12 and a bogey at 16 after his 6-iron from 200 yards landed short and left of the green.
"I wasn't as prepared as I'm used to when I pulled back on the ball," Westwood said of his round.
"There was a little bit of doubt in there. I'll have to work on that for tomorrow."
It's not that Westwood isn't feeling a boost after capturing January's Abu Dhabi Championship for his 25th career European Tour victory.
"My confidence levels are high," he said.
"Any time you win a tournament like I did in Dubai, your confidence has to escalate."
Sharing fifth on 208 were South Korea's Im Sung-jae, American Daniel Berger and South African Charl Schwartzel.
