Cape Town - Dane Paterson completed his 11th career five-for as the Cape Cobras extended their advantage at top of the 4-Day Domestic Series table by securing a five-wicket win over the Dolphins on the final day of their clash in Cape Town on Thursday.

The Proteas paceman claimed six for 63 in 25.3 overs to help set up a low-scoring chase of 171, with the home side reaching their target midway through the fourth afternoon to make it four wins from four in 2018/19.

They are now up to 99.86 points, over 30 points clear of the chasing pack, who all drew their round four games this past week.

It was another clinical performance by Ashwell Prince's side, who began the final morning needing three wickets as the visitors resumed on 265 for seven.

Paterson got two of them, removing Keshav Maharaj (6) and Okuhle Cele (4), with Vernon Philander (1/49) claiming the wicket of innings top-scorer Dane Vilas for 72 (121 balls, 7 fours) - the Dolphins lasting just 4.3 overs more at Newlands.

The chase did not go entirely according to plan for the home side with Man-of-the-Match Pieter Malan, who hit a century in the first innings, dismissed for a second-ball duck in the third over by Robbie Frylinck (1/4).

Zubayr Hamza (7) also fell cheaply leaving the Cobras on 20 for two.

But Janneman Malan struck 38 to lead the recovery and, even though Maharaj claimed three for 49, Kyle Verreynne's 46 and an unbeaten 43 from Aviwe Mgijima took the log-leaders to a comfortable victory.
