Durban - David Miller and Rudi Second hit half-centuries as the Sunfoil Series clash between the Knights and Dolphins was headed for a draw after three days at Kingsmead on Saturday.
Bad weather has wreaked havoc in the round four match on the east coast, with the entire day two washed out by rain on Friday.
Day three was much better with 69.4 overs sent down, although there was no play after tea due to a combination of bad light, rain and lightning.
When stumps were drawn early, the top-of-the-table visitors had reached 176/6 in reply to the 311 all out made by the hosts.
Proteas limited-overs star Miller, returning to his former franchise for the first time since his winter move to Bloemfontein, made 60 (105 balls, 6 fours, 1 six). Second hit an unbeaten 61 (125 balls, 8 fours, 1 six) and shared in a 107-run fourth-wicket partnership that rescued the Knights after some early trouble saw them slip to 46/3.
Senuran Muthusamy was the pick of the bowlers with 2/33, while another Proteas 20 and 50-over specialist, spinner Imran Tahir, collected 2/57.
That left the central franchise trailing by 135 with a day to play.
