Dec 6 (Reuters) - Norway’s Kristoffer Reitan heads into Sunday’s final round of the DP World Tour’s Nedbank Challenge at Sun City with a commanding five-shot lead, but will rue a double-bogey at the last in his otherwise faultless 67.

Reitan, 27, who turned professional in 2018, is on course for a second victory on the European circuit after claiming a play-off win in Belgium's Soudal Open in May.
