Brandon Stone will take a 3-shot lead into the final round of the Alfred Dunhill Championship, when he'll have defending champion Charl Schwartzel for company, after a second successive 66 took him to 17 under overall.

The 23-year-old Stone, who led by one overnight, made most of his birdies in clutches on Saturday, three in a row on the front nine and three in four holes on the back to move clear of Schwartzel, Chris Hanson and Keith Horne. Those three chasers are all 14 under.

Overall, Stone had seven birdies and a bogey around Leopard Creek Country Club.

Schwartzel, the defending champion and four-time winner, found a hot streak with four straight birdies from Nos. 10-13 and six overall, but he also had two bogeys in his 68.
