World number three Jordan Spieth and Britain's Andrew "Beef" Johnston charged up the leaderboard in today's rain-hit second round of the PGA Championship while British Open victor Henrik Stenson stumbled back.
Stenson carded a second consecutive 67 at Baltusrol to claim the clubhouse lead on six under par, a shot ahead of Ryder Cup team-mate Martin Kaymer and America's Patrick Reed, whose 65 equalled the lowest score of the week.
Tied for second on five-under were 2010 PGA victor Martin Kaymer of Germany (69), Patrick Reed (65) and his fellow American overnight leader Jimmy Walker, who was teeing off in the afternoon.
He dropped back with a four-foot par miss at the third hole for his first bogey of the round but sank a four-footer for birdie at five to rejoin the leaders.
One stroke behind the big Swede on five-under were 2010 PGA victor Martin Kaymer of Germany (69) and Patrick Reed (65).
British Open champion Henrik Stenson birdied three of his last seven holes for a 67. He is grouped for the first two rounds with this year's other major champions, Danny Willett and Dustin Johnson.
He was tied with Emiliano Grillo who had a 4-under 32 on his front nine and then made three straight pars.
Once play ends, field will be reduced with the cut line likely 2-over par, although it could be 1 over.
Day's playing competitors Rory McIlroy and Phil Mickelson did not fare as well.
Fowler's opening round left him tied with defending champion Jason Day.
"More time made it easier to recharge, but at the same time I feel I can carry that momentum I had at the Open Championship, and I guess the start shows that we're not too far away when we teed it up again". "(I) had not been making a lot of putts this year", said Walker, who needed only 25 putts in his round.
"I struck the ball beautifully today", Spieth said.
"It's all about being there for Sunday afternoon, and so far so good", Stenson said. His lone blemish was a bogey 4 on No. 12.
Kaymer says it's understandable how he would have a dip in performance after major wins that could turn into a two-year win drought. It's going to be a great season for me, but at the same time I want to give myself a chance to try to make it the best season.
Referring to his own 2016 season, which has not featured a top-five finish since February 1 and has included missed cuts at the USA and British Opens, Walker said, "It's just been real stale and stagnant". "I think you saw out there, there was a couple of putts from quite a short distance that I left short". It marked the first time McIlroy went without a birdie since his 77 in round three at the 2016 Masters. "The people helped to really kind of pick me back up". Kaymer and Stenson both had to deal with those conditions and both still played well.
The other members of his group, Sergio Garcia and Bubba Watson, weren't able to get their rounds going.
Thirty-five players bettered par in the opening round and the early starters kept up that pattern, crowding the leaderboard before the afternoon wave, whose tee times were pushed back 45 minutes due to the rain delay.
