JOHANNESBURG, South Africa (PA) -- Charl Schwartzel, Andrew McLardy and David Drysdale share the lead going into Sunday's final round of the Joburg Open after the trio finished a rain-affected third round on 11 under par. The tournament is co-sanctioned by the European Tour and the Southern Africa Tour.

A second consecutive day of lightning and rain meant that three hours were lost in two separate interruptions at the Royal Johannesburg and Kensington Golf Club, but it did not stop South African Schwartzel from producing a sizzling 8-under 63.

His countryman McLardy and Scotsman Drysdale, who led at the halfway stage, were less impressive, though, with both picking up birdies at the last for rounds of 69 and 71, respectively, to ensure a share of the lead.

Retief Goosen, Joakim Haeggman and Anders Hansen lead the chasing pack at 10 under, with no fewer than seven players a further stroke back, including Britons Danny Willet and Michael Hoey, who both had poor rounds of 71 and 72 to slip down the leaderboard.

But it was Schwartzel who made the biggest move of the day in an eventful round that included an astonishing 10 birdies, a hole-in-one, two bogeys and also a double bogey as he ripped through the East Course.

He picked up seven shots through his opening 10 holes, before a double bogey on the par-4 11th was followed by a sublime 7-iron on the par-3 205-yard 12th that dropped a foot from the and rolled in.

"What a day! The first 10 holes, I felt pretty flawless," said Schwartzel, the world No. 68. "Nothing could go wrong, I was hitting the ball close, I wasn't making any long putts, I was just hitting it four foot from the hole every time.

"You know, 7 under, I was thinking maybe I could make 59 today," he admitted. "And that came to a quick halt on the very next hole. I made double and then I was sort of almost ready to walk off the golf course right there. But then on the next hole I made a hole-in-one and was celebrating. So it was really nice.

"My rain delay went well today," he said. "I managed to make my two birdies, which just put a smile on my face."

Two-time major winner Goosen was faultless through his third round, firing a 6-under round of 65 and was especially impressive at the turn, where he picked up four birdies in six holes between holes eight and 13.

"Yeah, it was good coming off the back nine. The first two rounds I had bad back nines," he said. "I had good front nines then blowing it on the back nine, so it was good to get a nice finish in.

"It's a great golf course and the first four holes are the toughest you will find on any golf course," he added. "I got through those in par and then it was good to get a couple of birdies going on the par 5s.

"It's going to be an exciting start tomorrow. The first four holes I must try to be par or make one shot better, then I can gain on the field."

Hansen, who followed his 71 and 68 on the opening two days with a 64, said: "Today I was trying to get there, somewhat closer to them (the leaders).

"I was a bit far behind, especially after the first round when I had a terrible start," he added. "But I got myself back into the tournament, so we'll see what happens."

Defending champion Richard Sterne managed two birdies in his last two holes to move to 6 under and keep his hopes of winning a third consecutive European Tour title alive, while Englishman Chris Wood completed his round in 72, dropping to 2 under for the championship.
