Former Ryder Cup star Henrik Stenson holds a three-shot lead after the third round of the South African Open at Serengeti.
The Swede held a four-stroke advantage after two rounds and a three-under 69 on Saturday kept him in control.
Stenson collected four birdies on the front nine with only one bogey while he was par for course on the back nine, although he birdied the 15th and 17th.
The biggest mover of the day was South African George Coetzee, who fired a course record 63 to jump to 13-under and into a tie for second.
The 26-year-old was six-under par on the front nine, with four birdies and an eagle on the fifth, a hole which Stenson bogeyed.
Joint-second with Coetzee is another Swede, Magnus Carlsson. He birdied three of the last four holes to shoot a 68. Darren Fichardt - another of the home contingent - is in fourth spot three strokes further back at 10-under.
Germany's former world number one Martin Kaymer moved into a share of sixth place with a 68, but still has eight shots to make up, while last year's Masters champion Charl Schwartzel was 10 behind after a scrappy 74 that included two early double bogeys and two closing bogeys.
Among those alongside him in 13th place was England's Tommy Fleetwood, for whom every shot is crucial as he tries to climb from 124th on the Tour money list into the top 119 who keep their cards.
Scot Lloyd Saltman had to win to earn his 2013 place, but a 75 dropped him from fourth to 20th.
Fellow countryman Craig Lee did even worse with a 77 to be in a tie for 38th, but at 116th on the Order of Merit he may have done enough already.
