(CNN) -- Swedish duo Johan Edfors and Mikael Lundberg both carded six-under-par rounds of 66 to share the lead after a weather-affected first round of the Abu Dhabi Championship on Thursday -- reports the official European Tour Web site.
Johan Edfors shares the lead after a wet opening round of the Abu Dhabi Championship.
Play was held up for over two hours after a hailstorm flooded the course and although the storm was brief, it was so fierce that the greenkeeping staff had to clear flooded bunkers and fairways.
The two hours lost meant that around half the field were still to complete their opening round when darkness brought the day's play to a close.
Another Swede, Jarmo Sandelin, was a shot further behind on five-under-par, alongside England's Oliver Fisher and Italy's Francesco Molinari, while holder Martin Kaymer is in the frame, having completed a first round 68.
"Not as good as last year but I'm very happy," the German told europeantour.com. "I didn't hit the ball very well but my putting was awesome, so that gave me a lot of opportunities to make birdies. I'm happy."
Alongside Kaymer are Rafael Cabrera Bello, Jean-Baptiste Gonnet, Richard Green and Joburg Open runner-up Andrew McLardy.
Three-time major winner Padraig Harrington, playing his first European Tour event of 2009, recorded a respectable one-under-par 71. "I felt reasonably good, towards the end of my round," said the Irishman.
Another major winner last year, Trevor Immelman, posted a level-par 72. "I actually felt like I hit some nice shots but couldn't get the putter to co-operate, so I need to work on that," said the South African.
On the course, South African Louis Oosthuizen is five-under with two holes to play, while Spaniard Ignacio Garrido is also five-under with three holes to go.
World No.2 Sergio Garcia made a fantastic start, moving to three-under after just five holes after starting his round with consecutive birdies. The Spaniard was still three-under when bad light brought his day to an end with four holes remaining in his first round.
Meanwhile, former U.S. Open champion Angel Cabrera fired a superb 10-under-par 62 to take a one-shot lead after the first round of the Africa Open.
Cabrera carded nine birdies, an eagle and one bogey to top the leaderboard at East London Golf Club. Canada's Graham de Laet is a shot behind after a 63 with another former U.S. Open champion, Retief Goosen, three shots further back on six-under.
