Australia’s Jason Day, who is competing in his first PGA Championship, shot a three-under 69 to take the clubhouse lead in the first round of the weather-hit final major of the season.
Day was in the opening group that teed off from the 10th hole but he had to wait over three hours to get started because of a fog delay.
He finished with five birdies and made the turn at 34 on the Whistling Straits course.
The 22-year-old from Forest Lake, Queensland is one of three Australians within a couple shots of the lead, joining countrymen Michael Sim and Marc Leishman near the top of the leaderboard.
On the course, Bubba Watson was four-under through 16 holes.
Leishman and Sim were both three-under on the course.
Birdies for Tiger Woods
Tiger Woods opened his round with three birdies on the first four holes but was one-under through 14.
Day played in a group with Tim Petrovic and Rich Steinmetz. They had to wait three hours and 10 minutes to get going after dense fog from Lake Michigan blanketed the course early Thursday.
Day birdied his 17th hole of the day – the par-four 507 yard eighth – to move to four under and into a tie for the lead before giving one shot back with a bogey on his final hole.
He opened his round with four pars then birdied two of the next three holes.
Day qualified for the PGA Championship by winning the Byron Nelson Championship in May. He finished tied for 60th at the British Open at St. Andrews.
Tiger Woods in better form
Woods, who is fresh off his worst career performance at the Bridgestone Invitational, needed just four putts on the first four holes after starting his round off the 10th tee.
Woods is playing with defending champion Yang Yong-eun and 2004 PGA Championship winner Vijay Singh.
Wearing a white shirt in the muggy conditions, Woods’ approach from 80 feet out on the par-four 361-yard 10th hole landed on the green before snaking in a 10 foot putt for birdie.
Woods hit another superb tee shot on his second hole and followed it up with an iron shot landed 10 feet from the pin.
His first errant shot came off the tee at No. 12 as he put it over the green and across a public path, but he was able to recover and get his second shot on the green and save par.
Woods’ game has hit the skids coming into the final major of the season when he shot a fourth round 77 to finish in a tie for 78th at the Bridgestone — a tournament he had won seven times before.
Woods made the turn at 34 then dropped a stroke back
The four-time PGA Championship winner is without a win this season and without a major title in the past two years as he battles to rebuild his career and reputation following the sex scandal which engulfed him last November.
Even before the fog struck Thursday morning, the par-72, 7,507 yard course had been hit by bad weather.
Thunderstorms dumped more than four centimetres of rain on the course Wednesday, forming puddles in many of the close to 1,000 bunkers and softening the fairways and greens.
