Italian Francesco Molinari fired a four-under 68 to seize a share of the lead with American Bubba Watson in the first round of the weather-hit PGA Championship, but Ernie Els was on the same score when play was halted due to fog.
Els and Matt Kuchar of the USA were also at four-under when play was halted for the day because of darkness following a three hour, 10 minute delay at the start of the round due to dense fog.
Els got a ride back to clubhouse as the evening light faded over the course and he found himself stranded on the par-four 15th hole when the siren sounded.
The 78 players who were left on the course will complete their rounds Friday followed immediately by the second round of the 7.5 million dollar event.
Tiger Woods rolled in a birdie on his final hole to get to one-under 71. The 14-time major championship winner is three shots back of the leaders in a group that also includes Molinari's brother, Steve Elkington, Brian Davis and Camilo Villegas.
World number two Phil Mickelson was one-under par through 11 holes and is tied for 24th. Mickelson revealed this week he is being treated by doctors for debilitating arthritis which at one point a couple of weeks ago left him unable to get out of bed.
Weather forecasters are predicting more fog today.
