Mikko Korhonen produced a third successive bogey-free round to open up a five-shot lead on day three of the Shot Clock Masters.
Finland’s Korhonen, who has never won a tournament since turning professional in 2004, made birdies at the first, third, ninth and 10th holes to sign for a four-under-par 68, moving him onto -13.
The 37-year-old now has a massive five-shot advantage heading into Sunday’s final round at Diamond Country Club after the rest of the field were unable to mount any real charge.
South African Justin Walters, a two-time Sunshine Tour winner, is in sole possession of second on -8 after shooting a level-par 72 whilst there are no less than eight players a shot further back on -7.
Australian Adam Bland, England’s David Horsey, Scotland’s Connor Syme, Canadian Austin Connelly, Sweden’s Peter Hanson, China’s Ashun Wu, Denmark’s Jeppe Pape Huldahl and Spaniard Miguel Angel Jimenez are all six shots off the pace.
Englishman Lee Slattery shot a brilliant six-under-par 66 to move into a six-way share of 11th on -6 alongside Swedish pair Oscar Lengden and Oscar Stark, Frenchman Raphael Jacquelin, Australian Nick Cullen and Austrian Matthias Schwab.
