South African Richard Sterne cruised to a seven-stroke victory over former US Masters champion Charl Schwartzel Sunday in the Joburg Open.
Sterne, runner-up behind Stephen Gallacher of Scotland in the Dubai Desert Classic last weekend, fired an eight-under final-round 64 for a total of 260 in overcast conditions at Royal Johannesburg and Kensington Golf Club.
Pre-tournament favourite Schwartzel, who won the Joburg Open in 2010 and 2011 before relinquishing the title to Branden Grace last year, finished with a 66 for a 267 total over the 6942-metre course.
Chilean Felipe Aguilar (67), South African George Coetzee (67) and Portuguese Ricardo Santos (64) shared third place on 268 in the $1,758m event co-sanctioned by the European Tour and Sunshine Tour.
South Africans Thomas Aiken (66), joint overnight leader Trevor Fisher junior (73) and Keith Horne (65) were a shot further back and Italian Lorenzo Gagli (67) and South African Garth Mulroy (67) ended with 270 totals.
The final round at a course in an upscale north-eastern Johannesburg suburb was disappointing with the expected showdown between overnight leaders Sterne and Fisher failing to materialise.
Fisher fell away badly after an eagle on the opening hole and a bogey-free eight-under round brought a sixth European Tour title to Sterne, who has been hampered by back problems.
"I played really good golf today and throughout the tournament -- that was probably the best final round of my career," said Sterne, 31, who missed much of the 2010 and 2011 seasons due to a form of arthritis.
"This is a big year for me. I have got off to such a nice start and hopefully I can keep it going. I desperately want to get back into all the Major championships.
"After so much time out with injury I did wonder whether I was ever going to win again. At one point the pain was so bad that I even wondered if I would ever play golf again."
Sterne laid his victory foundations on the front nine with five birdies - including three in a row from the sixth - while Fisher followed his eagle with three bogeys and a birdie by the turn.
A further three birdies on the inward half consolidated the advantage Sterne had created while a double bogey on 11 after a drive into trees and a second into a stream spelt the end for Fisher.
