After a clean sweep in the foursomes, South Africa looked on track to score full points in the fourballs, but Krogg and Allard had the measure of the greens at Devonvale Golf and Wine Estate and handed the SA pair a 3 and 2 drubbing.
South Africa kept ahead in the log with 15 points, but the local favourites may have to pull out all the stops in the final round singles to secure the country’s 19th title in Africa’s most prestigious team championship.
Looking to go one better than their runner up spot last year, Zimbabwe pulled within three points of South Africa and sits comfortably in second place.
But Zimbabwe is not the only threat.
Namibia also made a major move with three foursomes victories and a clean sweep in the fourballs to finish just a half point behind Zimbabwe.
Swaziland slipped into fourth on the log with 9.5 points alongside Mauritius, while Kenya and Malawi lurk just a half point back in sixth.
