Sterne cruises to Joburg Open title by 7 shots

Sterne shot a bogey-free 64 to finish with a tournament record total of 27 under at the Royal Johannesburg & Kensington golf course and win by the largest margin in tournament history.

"That was probably the best final round of my career," Sterne said. "It was quite special to finish the way I did."

Fellow overnight leader Trevor Fisher Jr. faltered on the final day, allowing Sterne to finish well clear of Charl Schwartzel (66) in second. Fisher eagled the first but sank to a 1-over 73 that dropped him to joint sixth, despite sitting five shots clear of the field with Sterne at the start of the final round.
