There are nine South Africans among under 65 on Saturday.

Otto finished 54 holes at 14-under 202 to take a three-shot lead into Sunday's final round and will try for his second European Tour title. His first came in 2008 at the Italian Open, where he also had the lead after three rounds.

It's Otto's fourth 54-hole lead overall, failing to convert each of the first two times. He recovered from two early bogeys to finish with an eagle and seven birdies to surge ahead.

He'll be paired with two-time champion and fellow South African Retief Goosen on the final day. Goosen shot a one-under 71 to get to 11-under, but it came after a start of three straight birdies.

Goosen's finish was rather dismal, posting back-to-back bogeys to squander a chance to share the lead. He had five birdies and four bogeys overall at Serengeti Golf Club.

Goosen shares second with Magnus A. Carlsson (66), Thomas Aiken (68) and Garth Mulroy (70), who won the Alfred Dunhill Championship last week. Merrick Bremner (72) and Jaco Ahlers (65) are four shots back, tied for sixth at 10- under.

Second-round leader Steven O'Hara, who needs a good performance to retain his tour card, didn't do anything to help himself Saturday. He shot a two-over 74, slipping into a share of eighth at minus-nine with seven other players.
