China'a Li Haotong withdrew from the PGA Championship before the second round resumed on Saturday morning due to a wrist injury, the PGA of America announced.
Sirens blared across Bellerive, putting the second round of the PGA Championship on hold and ending a day of scoring rarely seen in a major.
Woodland added a 66 to his opening 64 to complete 36 holes at 130, the lowest total in the championship's 100 years and bettering the mark of 131, which had been shot nine times. After two holes in his first round, he was three-over par.
US Open champion Koepka and Schwartzel both missed putts on the last for 62s that would have equalled the lowest round in a major.
Rickie Fowler, who says he's playing with an oblique strain, is also a 7 under through 10 holes.
TV: 8 a.m.to 2 p.m. ET on TNT and 2 p.m.to 7 p.m. on CBS.
But it means a long day of 28 holes for the 42 year old on Saturday, the first time he will have played more than 18 holes in one day in this latest comeback. "But the nice thing about the delay and going back out tomorrow morning, we'll get fresh greens".
Tiger Woods to play in his first PGA Championship in 3 years
The only player with better odds to win the 100th edition of the PGA Championship this week is World No. 1 Dustin Johnson . Ryder Cup: The PGA Championship is the final event for players to finish among the top eight qualifiers for the U.S.
Woodland's 36-hole score broke the PGA record by one shot, most recently set by Jimmy Walker and Robert Streb at Baltusrol.
Lowry, whose best major finish was tied second at the US Open in 2016, holed a 24ft putt for birdie at the par-three third to get to five-under before two gains over the closing three holes put the polish on his round. Unfortunately, Finau carded a triple bogey on the par-3 6th hole, which brought his cut probability back down to 50 percent. "The key is to get the ball in the fairway and attack from there".
World No 9 Fowler, chasing his first major title, completed a three-under-par 67 to join compatriot Brooks Koepka at the eight-under mark, while Lowry sits at seven-under after compiling a flawless six-under 64 with Thomas a shot further back.
"There have been ups and downs and I just feel like I'm starting to play a better golf game". The golf course is gettable and I'm holing a few putts. "I didn't know if it was going to cover enough, but it looked like it just covered the bunker and rolled up there to about 5 feet".
"I don't really feel from memory that I was ever really in contention on a Sunday at the PGA, although I've had some good results", Scott said. "I hit it well on the second nine".
Woods hit his drive at the fourth hole into thick rough to the left of the fairway, and he took a furious rip into the thick grass to advance the ball up the fairway at the par-4.
