The Free State Knights beat Western Province by 38 runs at Newlands on Friday.
Needing 305 to win, WP fell well short despite half-centuries from Yaseen Vallie (50 off 80 balls), Daniel Smith (59 off 60) and George Linde (55 off 46). Their innings ended with nine balls still remaining.
Alfred Mothoa (3-47) was the pick of the Knights bowlers.
Earlier, Free State posted 304-6 in their 50 overs with Matthew Kleinveldt (68 off 84 balls), Raynard van Tonder (54 off 78), Rilee Rossouw (48 off 31) and Patrick Kruger (53* off 34) all making important contributions.
Mihlali Mpongwana took 3-61 and Tshepo Moreki 2-66 with the ball for WP.
In Potchefstroom, the Boland Rocks beat North West Dragons by 27 runs.
Stiaan van Zyl (114* off 141 balls) and captain Pieter Malan (98 off 110) took Boland to 200-2 after 43 overs, but Malan’s run out triggered a collapse and they finished on 251-8. Most of the damage with the ball was done by Eldred Hawken, who finished with 6-46.
However, that total proved to be enough as the Dragons were bowled out for 224.
Wesley Marshall (73 off 87 balls) top-scored for the hosts, while Achille Cloete and Hardus Viljoen each picked up three wickets for the Rocks.
In East London, the Division 2 match between the Eastern Cape Iinyathi and Eastern Storm was abandoned without a ball bowled due to rain.
