Knights survived an early onslaught by Impi opener Luke Wright to grab a vital four points with a five-wicket win in a rain-affected game at the De Beers Diamond Oval in Kimberley. Still chasing their first win in the competition, Impi chose to bat and Wright (75 off 39 balls) showed the way by taking 20 runs off Ryan McLaren's sixth over. Along with Ryan Canning (36), he brought up a century opening stand in the ninth over. However, the introduction of left-arm medium-pacer Jander Coetzee (4-34) slowed the proceedings and the Paul Collingwood-led Impi side finished with 178 runs. For Knights, Rilee Rossouw (42) and Morne van Wyk (34) led the response to take the home side to within 22 runs of the target in 17 overs, when the rain came. Knights were ahead of the D/L target at that stage. With no further play possible, Knights won the game and are comfortably placed to qualify for the semi-finals.

Pre-tournament favourites Cape Cobras disappointed in their crucial match against Warriors, losing by 43 runs at Newlands, Cape Town, a day after their allrounder Rory Kleinveldt was withdrawn from the squad for testing positive for a banned substance. Cobras chose to bowl and restricted Warriors to 149 with Brad Hogg taking 4 for 33. In reply, Warriors' bowlers shared the spoils to dismiss Cobras for 106 runs in 18.5 overs.

The game between table-toppers Lions and fifth-placed Dolphins at the New Wanderers Stadium in Johannesburg was abandoned after 6 overs, as the pitch was not fit for play due to the adverse weather conditions in the past few days. Both teams were awarded two points each.
