The Dolphins and Knights have secured the first spots in the Momentum One-Day Cup semi-finals after a third consecutive Pool A match was abandoned due to rain.
The two teams were due to meet in the final pool clash in Potchefstroom on Saturday, but once again persistent rain and a wet outfield meant play was called off without a ball being bowled.
As a result, the Dolphins finished top of the group with 13 points, while the Knights ended in second spot with six points. The Titans narrowly missed out on qualification having secured five points from the pool stages.
The Dolphins and Knights will face the top-two teams from Pool B, who will begin their set of matches on 22 January, also at Senwes Park. The Lions, Cobras and Warriors will arrive in the North West town on Tuesday.
