Sergio Garcia continued his remarkable recent run of form as he opened up a two-shot lead heading into the final round of the Nedbank Golf Challenge in South Africa.

The Spaniard's play in the early part of 2018 was so poor that some saw him as a risky selection for a Ryder Cup wild card but he has not looked back since being selected by Europe captain Thomas Bjorn.

He finished in the top 10 at the Portugal Masters, won three points in the victory at Le Golf National to become the competition's all-time highest points scorer and then successfully defended his title at the Andalucia Valderrama Masters.

The 2013 Masters champion led after days one and two in Sun City and a third-round 71 moved him to 10 under, two shots clear of fellow major winner Louis Oosthuizen.

It was a disappointing day for Shane Lowry, who struck a two over par round of 74 but remains the best of the Irish contingent on -2 for the tournament. 

Padraig Harrington, likewise, hit a 74 to fall to four over par for the competition. Rory McIlroy was only marginally better and his round of 73 leaves him at even par for the tournament. 

Paul Dunne, who effectively dropped out of contention with an opening day 78, actually enjoyed the best day of all the Irish players, his even par round of 72 leaves him sitting at five over par heading into the final round.

England's Lee Westwood was then at seven under alongside Belgian Thomas Detry and Finn Mikko Korhonen, with another Englishman in Ross Fisher a further shot back.

"It's going to be tough, there's no doubt about that," Garcia said. "But it's great to come with some good momentum, playing nicely and in the lead. It should be a fun day.

"I think if I can manage to shoot somewhere in the 60s, maybe 70 might be enough. I'm going to see if I can shoot below 70 and see if that's good enough."

Garcia - a winner at this event in 2001 and 2003 - birdied the par-five second and hit a stunning approach into the third for back-to-back birdies and a three-shot lead.

He got in tree trouble on the 13th but birdied the 17th after another excellent approach before sending his second into the stands for a closing bogey.

Oosthuizen, the 2010 British Open champion, made two birdies and two bogeys to lead the home charge after a 72 while Westwood - winner here in 2010 and 2011 - signed for a 69.

Fisher dropped eight shots in his last four holes on Friday but recovered admirably with a third-round 67.
