On a pitch growing ever lower and slower, Matthew Olsen drew first blood by dismissing both Robertson openers in successive overs with his off-breaks.
Brendon Erasmus was the sole batsman on either side to deal with the conditions successfully, producing a run-a-ball knock of 45 that ultimately represented almost half the home side’s runs.
The statistical highlight of the match was Darren Rolfe’s 300th career wicket for the Cape Town First XI, a milestone suitably achieved by castling Robertson’s key batsman Brendon Erasmus.
Robertson took the field with a seemingly moderate total of only 115 to defend, but opening bowler Warwick Abrahim put them immediately on top with a spell of 3-1-5-2.
With Cape Town already deep in the mire at 48-4 after ten overs, Robertson leg-spinner Amre Konstabel then put the game’s outcome beyond any reasonable doubt by striking in each of his first two overs.
With his opponents needing an all-but-impossible 50 from the last five overs, with seven wickets down and a low, slow pitch to contend with, Robertson captain Ferisco Adams rubbed further salt into Cape Town’s wounds with a wicket in each of his final two overs as he returned to close out the game at the death.
Having already played the major role with the bat in ensuring a defendable total, Brendon Erasmus the added the finishing touch by claiming the final wicket with his off-spin too.
Celebrations for Robertson as the home side wrap up their second comfortable win of the day, thereby booking their place as the Cape Cobras representative side in the national T20 Community Cup tournament.
