England's Anthony Wall earned a share of the lead at the Joburg Open with a flawless 68 in the third round on Saturday.

The 40-year-old one-time winner on the European Tour had birdies on the fourth, ninth, 10th and 13th holes, and will head into Sunday's final round level on 15 under par along with South African pair Zander Lombard and Haydn Porteous.

Lombard had an even more eventful and productive day at the office. The Pretoria-based player, who turns 21 on Monday, posted nine birdies and two bogeys en route to a 65 on the East Course at Royal Johannesburg and Kensington Golf Club.

And Porteous, having started with an eagle at the par-five first, then ended his third round with two straight birdies to make it a three-way tie at the top after 54 holes.

Wall's only other career victory came at the Alfred Dunhill Championship in 2000, and he acknowledges his approach to the game has changed in the past 16 years.

"That's why I play golf now -- to try and make my children proud of me, to try and win as many times as possible," he told the European Tour's official website.

"At the end of the day I'm a father now before I am a golfer. That switched a few years ago and I just want to keep playing for them and my wife so they can be proud of me."

England's Ross McGowan -- the halfway leader by three shots after a sparkling 62 on Friday -- fell away with a 73.

He had four birdies, but three bogeys plus a double-bogey six on the par-four seventh saw him slip off the pace.

McGowan was by no means out of it heading into Sunday, however. He will go into the final round one of four players two shots adrift of the leading trio -- along with Ireland's Paul Dunne (68), South African Jacques Blaauw (67) and American Daniel Im (65).

On Saturday's bogey-free round, Wall added: "I drove the ball well. That was my weakness the first two days. Today I was great off the tee. I holed a couple of good long ones, but I also missed three or four I could have holed, so all in all it was a good day.

"I've got a great chance [on Sunday]. But they're all good players. Someone's going to be a little luckier [on Sunday] and win, so hopefully it's me."

Wall secured his place at the 2015 Open Championship by finishing second in this event last year, and could do the same this year.

The leading three non-exempt players in the top 10 will qualify for the 2016 Open, with only Ernie Els, David Howell, Paul Lawrie and Jaco Van Zyl currently assured of their places at Royal Troon.
