A golfer known for being one of the longest hitters on the PGA TOUR is halfway to winning his first major championship because of his putter.

Gary Woodland shot a 4-under 66 and holds a one-shot lead over Kevin Kisner after two rounds of the 100^th PGA Championship at Bellerive Country Club outside St. Louis.

Seventy-eight players were unable to complete the second round when afternoon storms chased them off the course. After a two-hour delay, officials suspended play for the day.

The second round will resume Saturday at 8 a.m. EDT. The third round will begin at 12:15 p.m., with threesomes starting at the No. 1 and No. 10 tees.

Of the players from Australia in the field, nobody was better than Adam Scott, who parlayed a six-birdie, one-bogey day into a 65 that moved him five shots behind the players who finished their rounds.

Jason Day was solid Friday, at 1-under through eight holes and 4-under overall.

Marc Leishman went in reverse, shooting a 1-over 71, leaving him tied for 49th at 1-under in his 36 holes.

PGA professional Craig Hocknull (1-over through 12 holes and 3-over total) and Cameron Smith (even for the day through 11 holes and still 4-over) are in danger of missing the cut.

“I felt like I was at The Open teeing off Sunday. It’s definitely moving in the right direction, and 65 at a major is always a good score,” said Scott.

“I kind of said last night I felt like there was a 65 in the way I was playing, and[I] just have to do it.

“I made a couple of extra putts for par today to keep the momentum going, and that’s probably the difference between most of my golf generally over the last 12 months.”

New Zealander Ryan Fox played 12 holes and moved from 2-under to 3-under before officials halted play.

Woodland, who shot 64 in the first round, played alongside Kisner, who carved out a 64 and stands at 9-under 131. U.S. Open champion Brooks Koepka shot 63 and is alone in third place at 8 under.

Woodland averaged 317.7 yards off the tee, which enabled him to reach the 597-yard 17th hole in two shots and led to a rare eagle there. But it was his stroke on the greens, where he gained 3.6 shots, that kept him in front.

“For me as a whole, the putting was kind of the last piece of the puzzle,” Woodland said.

“When I drive it in play, I’m playing a game a lot of guys aren’t playing out here, and that’s a huge advantage. Once that started to come around, really the putting was the last piece.”

Woodland has been working with putting coach Phil Kenyon. There was great progress shown at The Open Championship, where Woodland contended, and it has continued.

“Today I felt like I putted it as good, if not better, than I did yesterday,” he said. “I just didn’t see putts go in, but I can live with hitting good putts.”

Kisner, who last month had a share of the lead for three rounds at The Open Championship, shot 29 on the front nine to charge up the leaderboard. He was tied for the lead until making a bogey on his final hole. Kisner contended at last year’s PGA Championship at Quail Hollow in Charlotte, N.C., and finished second, his best finish in a major.

“All I know is if I hit it in the fairway and hit it on the green and make the putt, I’m probably going to have a good shot at it,” Kisner said.

“That’s all I’m going to keep trying to do. I’m not going to get too caught up in it.”

Koepka and Charl Schwartzel, the 2011 Masters champion, tied the PGA Championship scoring record, with 63s.

Koepka’s round started when he holed out from the fairway for a birdie on the first hole. He is trying to become the first player two win two majors in the same season since Jordan Spieth in 2015 and the first player to win the U.S. Open and the PGA Championship in the same year since Tiger Woods in 2000.

“It would be special and especially where I started the season,” said Koepka, who began the year with a wrist injury that kept him out three months and prevented him from playing the Masters.

Schwartzel is tied for fourth, at 7-under, with the world’s No. 1 player, Dustin Johnson, and Thomas Pieters, who each shot 66, and Rickie Fowler, who was at 7-under through 10 holes when the storms hit.

Defending champion Justin Thomas was 1-under through seven holes and 2-under for the tournament when play ended for the day.

Tiger Woods was another player who got caught in the storm. He was 3-under through his first seven holes and 3-under for the tournament.

Phil Mickelson was 3-over through eight holes and was in danger of missing the cut, which was expected to fall at even-par.
