South Africa will look to extend their record-breaking run of wins to 13 when they take on Sri Lanka in the fourth ODI, live on Sky Sports 2, in Cape Town.
The Proteas made it 12 ODI wins in as many home games with a comfortable win in Johannesburg to take an unassailable 3-0 lead in the five-match one-day series.
However, AB de Villiers is keen that his side do not ease off in the two remaining games before they fly out for their tour of New Zealand.
"There were too many 3-2 results in the past and we've had many opportunities to win series 5-0 and 4-1," he said after the third ODI. "We are all a bit sick and tired of not taking our opportunities and we are sitting here with another opportunity."
"We try to be clinical about every game we play, with a bit more emphasis and importance on getting results in every single game we play and not just trying to win a series.
"Having said that, I don't want to mention it too often and I don't want to make it our main thing that we play for 5-0 whitewashes, because that can backfire quickly."
De Villiers also has a tough decision to make when it comes to his all-rounders after Dwaine Pretorius' man-of-the-match performance at the Wanderers, with Chris Morris and Wayne Parnell fighting it out for the other spot.
Meanwhile, Sri Lanka may bring Chaturanga de Silva into the middle-order to replace the out-of-form Dhananjaya de Silva.
Watch the fourth ODI between South Africa and Sri Lanka from 11.25am on Tuesday, Sky Sports 2.
