Stephen Gallacher and Ryan Fox shared the lead heading into round three of the 2021 Saudi International powered by SoftBank Investment Advisers but World Number One Dustin Johnson was just a shot back at Royal Greens Golf and Country Club.
With just over two hours lost to a dangerous weather situation on day two, many of the later starters had to return to complete their second rounds on Saturday morning.
Gallacher was among them and he played his final six holes in level par to sign for a 68 and stay alongside Kiwi Fox - who had completed a 65 on Friday - at ten under.
Johnson picked up a shot in his remaining four holes to sit one back after a 64, with fellow American Kevin Na, English pair David Horsey and Andy Sullivan, and Austrian Bernd Wiesberger at eight under.
Scot Gallacher - a two time winner on the Arabian Peninsula at the Omega Dubai Desert Classic - dropped a shot at the 13th with a three putt upon the resumption to hand Fox the solo lead but picked it back up from 20 feet on the 15th.
"It was quite tricky this morning," he said. "It was raining and cold and the ball wasn't going very far, so it was tough.
"I've played with Dustin before, so looking forward to playing with him. That will be nice to see. Always good to play with the world's best, see what they are doing."

Johnson birdied the par five last from 15 feet to stay bogey free for the week as he looks to regain the title he won at the inaugural staging of this event in 2019.
"I like this golf course a lot," he said. "I think it sets up well for me, I seem to play it okay. From the first time I played it, it set up good to my eye.
"It's got a mixture of golf holes on it. Some really difficult holes. And you've got to hit some really good drives and then you've got quite a few short ones too, where you have to take advantage."
Na started his day with five holes left and made a big move through the field, with birdies on the 14th, 16th and 17th making it five in six holes, before a bogey on the last saw him sign for a 63.
Round one leader Horsey had six holes remaining and picked up a birdie on the sixth, with Sullivan and Wiesberger having completed their rounds on day two.
Tony Finau and Joost Luiten each picked up a shot to move to seven under alongside Victor Perez, who stayed in that group, Marcus Kinhult, who slipped into it with a bogey, and Friday finishers Tommy Fleetwood and Calum Hill.
