The start of the final major of the year, the USPGA Championship, is delayed as heavy fog hangs over Whistling Straits, leaving players waiting on the driving range for their rounds to begin
American DJ Trahan takes advantage of the fog delay to indulge in a little bit of last-minute visualisation, or maybe enjoy a brief snooze, as the wait continues in Wisconsin
Play finally gets under way after a three hour, 10 minute delay but early starter Vaughn Taylor of the United States still has to deal with less than ideal conditions as he tackles the first hole
England's Luke Donald birdies the 10th - his first hole - to make an early impression on the leaderboard but he goes on to card a level-par 72 to finish a little off the pace
World number one Tiger Woods, who went in to the tournament on the back of his worst ever pro score, birdies three of his first four holes to suggest he has banished the demons and can mount a serious challenge
The early clubhouse leader is Australian Jason Day, who despite a final-hole bogey returns an impressive 69, featuring five birdies, to be three under for his round
Bubba Watson comes home one shot better off than Day as he plays his last nine holes in 33 shots. It's a round which includes some fine scrambling over the last few holes from the big-hitting American
Woods struggles to maintain his fast start but a birdie on the ninth, his last hole played, sees him go into the second round on one under after his first under-par round since The Open at St Andrews
A burst of three birdies in his last five holes gives Italy's Francesco Molinari, whose brother Edoardo is also in the field, a share of the lead with Watson. Can anyone get to five under as the shadows lengthen?
Floridian Matt Kuchar, who has eight top-10 finishes on the PGA Tour this season, started out at surprisingly long odds. He is four under after 14 when the hooter halts play
Four-time major winner and world number two Phil Mickelson shows miraculous powers of recovery to be one under after day one. The 2005 champion birdies 10 and 11 before the hooter intervenes
Northern Ireland's Darren Clarke continues his recent renaissance to be three under at the close of play. It could have been better though as he misses a short birdie effort at 13, his last hole of the day
Three-time major winner Ernie Els also finishes the day on four under par after 14 and looks in splendid shape. A victory this week would take him three-quarters of the way to completing a career grand slam
Nick Watney of California makes it a five-way tie for the lead on four under par with an eagle at 11 right on the hooter. There are 117 players within six shots of the lead heading into day two
And one of those players is Northern Ireland's Rory McIlroy - seen here with playing partner Adam Scott of Australia. McIlroy fought back from being three over after four to finish one under after 13
