Sweden's Alex Noren has moved into the lead at the Nedbank Golf Challenge after day two at the Gary Player Country Club.

A rain-affected second day saw Noren finish on five-under and make it eight-under for the tournament, overtaking former leader Ross Fisher, whose par round dropped him down to joint eighth.

Home favourite Louis Oosthuizen made the biggest stride towards the top of the leaderboard with a six-under round that left him two shots off Noren at the halfway stage.

Oosthuizen is one of five players in joint second on six-under, alongside Fabrizio Zanotti, England's Chris Wood and his fellow South Africans George Coetzee and Jaco van Zyl.

Zanotti had earlier created a slice of history with the first hole in one in the competition's history, briefly seeing him climb to the top of the leaderboard.

Masters champion Danny Willett suffered another forgettable day with two-over, though, further harming his hopes of winning the Race to Dubai.
