South Africa's Hennie Otto shot a 7-under 65 Saturday and took a three-shot lead after three rounds of the South African Open, capitalizing on stumbles by countrymen by Retief Goosen and Ernie Els.
Otto made seven birdies and an eagle, leaving him at 14 under at the Serengeti course. He is followed by four players -- Goosen, Sweden's Magnus Carlsson and South Africans Thomas Aiken and Garth Mulroy.
Goosen shot a 71 in a round marked by birdies on the first three holes and bogeys at Nos. 9, 13, 17 and 18.
Els, the defending champion, soared to a 76 and is tied for 53rd. He took a nine on the par-5 No. 16 after hitting his tee shot into the water.
Carlsson carded a 66 and is the lone player not from South Africa among the top seven.
