(CNN) -- Sweden's Henrik Stenson heads the Dubai Desert Classic leaderboard at the end of a second day heavily-disrupted by fog.
After the fog cleared Stenson shields his eyes as he prepares to tee off on the 11th.
Dubai resident Stenson shot a bogey-free seven-under 65 to lead on 11-under 133.
Australian Richard Green, like Stenson a previous Dubai winner, is one shot behind, but with just over half the field to complete their second rounds the position could change on Saturday when play resumes.
Green shot a brilliant nine-under 63 with world number two Sergio Garcia sitting two further shots back on eight under after a 66 from the Spaniard.
Just over six hours of play were lost to the conditions at the Emirates Golf Club, with 24 players unable to even start their second rounds.
"It was a grinding day," Qatar Masters runner-up Stenson told Press Association.
"But when I hit bad shots I recovered well and made some good birdies on the good shots so it was a very well-scored round."
First-round leader, Northern Ireland teenager Rory McIlroy, was a late starter but dropped back to seven-under alongside India's Jeev Milkha Singh after a bogey during his three holes possible.
In-form South African Louis Oosthuizen, European number one Robert Karlsson, Spain's Gonzalo Fernandez-Castano and Frenchman Gregory Havret are a shot further back on six-under after playing a handful of holes.
Tournament officials are hoping for better conditions on Saturday which would allow the third-round leaders to complete nine holes before returning on Sunday morning ahead of their final rounds.
But should fog again delay the start, officials will have to decide whether to extend the tournament until Monday or decide to cut the event to 54 holes.
The Desert Classic is the final tournament of a lucrative three-event "Gulf Swing", attracting a strong field as the Race to Dubai hots up.
