Ekurhuleni's finest young prospects might light work of the blustery conditions to combine for an opening total 382 to finish 18 strokes clear of Central Gauteng and 20 strokes ahead of KwaZulu-Natal.
Casey Jarvis, who returned for duty alongside Zama Nxasana and Yurav Premlall, set the tone for Ekurhuleni with an opening one-over-par 73.
"The conditions were really tough in the strong wind, but the players stuck to their strategy and it paid off for the team," said Ekurhuleni manager, Jack Turton.
"It's a very challenging layout and, with the strong wind this morning, we decided to play defensively on the holes against the wind and attack the holes playing with the wind. They executed the game plan well to put us in a very promising position
early in the championship."
Jarvis also grabbed a share of the first round lead in the Individual Competition alongside Southern Cape's Jan Human.
The 12-year-old from State Mines reversed a bogey start with a birdie at the second, and collected more gains at four, five, nine and 17 to offset a double bogey at the par-three 11th and further drops at six, 13 and 18.
