Kiwi Danny Lee is second in the Players Championship, seven shots back from Webb Simpson.
Simpson takes a seven-shot lead into Sunday's final round after shooting 68 to reach 19-under 197.
Simpson shook off a bogey at 14 and made pars at 15 and 16 before stepping up to the tee at the island-green 17th, where he had rinsed one Friday evening with the course record in his sights.
But even Simpson had a nagging feeling that he would be brought back to earth.
Asked if it can be hazardous for a player to play defensively, like an National Football League team playing prevent defense, Day said, "It can be unsafe - 100 percent".
Simpson was between a hard gap wedge and an easy pitching wedge, and after a long conversation with Tesori, made a decision to go with the gap wedge, aiming for a spot 138 yards away, up the slope of the green, short of the back-center hole placement.
A dropped shot on 18 looked, at one stage, like it would cost the 42-year-old, but he squeezed in under the cut line.
Cejka held a five-stroke lead after 54 holes but shot a closing 79 to plunge to equal ninth. - Webb Simpson has already etched his name into THE PLAYERS Championship record book. He planned to return on Sunday, when perhaps people will take notice. Simpson splashed out of the sand and hit a 100-foot shot that tracked into the hole for a magical eagle. He's also made 20 birdies. Barring a barrage of water balls at 17, Simpson might have one of the most stress-free Sundays in Players Championship history.

So I had to play an extraordinary match, and that's what I did. "I still have break point after", Monfils said . But Thiem managed to battle through to the third round in three sets 5-7 6-3 7-5, where he faced Borna Coric .
But Saturday was different, with Woods igniting the early morning gallery, covering his opening nine in 6 under par on his way to a 65, his lowest score to par on Tour in 1,744 days. The 65 was his lowest career score in 66 going around TPC Sawgrass.
"I wish I could repeat it more often, but honestly it was just a better start", Woods said.
Woods, a 79-times victor on the PGA Tour, used his irons with precision and wielded a hot putter to record his lowest numerical score on the PGA Tour since 2015. He'll enter Sunday with an even bigger lead. When the dust finally settled on a muggy day he was tied for ninth place.
He did, however, edge closer to Simpson over the last few holes. You have to think that, if given the option, you want the biggest lead you can have.
"It's rare as a golfer where everything is working well, driving, iron play, chipping and putting, and today everything came together. It's a hard golf course to press on", Poulter said. He was going along nicely, until he stumbled with a double bogey on the 18th, but he still managed to post a 69, and is very much continuing his recent run of form. "You're going to need to do what Tiger did on that front side tomorrow; you're going to need to be 6 under through nine". The most impressive shot of his day (and possibly the one that shut down this tournament) came on the par-5 11th.
Simpson started moving day at TPC Sawgrass with a five-shot lead and increased his advantage to seven shots courtesy of a four-under-par 68.
"It was a good solid round", Lee said.
