Cape Town - Attie Maposa returned career-best One-Day Cup figures to set the Dolphins on their way to a bonus-point seven-wicket win over the struggling Knights at the Kingsmead in Durban on Friday.
The medium-pacer claimed four for 46 to help bundle out the winless visitors for just 193, before Sarel Erwee led the way with the bat by striking 84 (109 balls, 13 fours) as the hosts eased to victory with 81 balls to spare.
It was a clinical performance by the Dolphins and helped them move level on 18 points at the summit alongside the Cape Cobras.
Maposa, whose best figures in the previous three matches he played were two for 22 against the Warriors earlier in the season, was the most successful of the bowlers, but there were other key contributions too after the Knights had won the toss and elected to bat first.
Senuran Muthusamy (2/9) and Calvin Savage (2/30) bagged two wickets apiece as the Central franchise struggled to get going.
They were three down for 22 in the eighth over and never really recovered, despite David Miller top-scoring with 79 (71 balls, 8 fours, 2 sixes).
Werner Coetsee scored 38 as the Knights folded in 41.5 overs.
Erwee
led the reply for the home side and, after he fell, captain Khaya Zondo
did the rest with an unbeaten 43 to take the Dolphins to a fourth win
in five games.
