The Proteas go into Wednesday's ODI series decider against Pakistan at SuperSport Park without five star players who have left South Africa for the Indian Premier League (IPL).
They will be without Quinton de Kock and David Miller in their batting order - they are likely to be replaced by Janneman Malan and Kyle Verreynne - but it is in the fast bowling department where the hosts will be particularly stretched with Kagiso Rabada, Lungi Ngidi and Anrich Nortje all unavailable.
Nortje, in particular, has been a shining light for his country having picked up a total of seven wickets from the opening two ODIs.
Fast, aggressive and relentless, Nortje was South Africa's chief destroyer in both matches and, speaking to media on Tuesday, national bowling coach Charl Langeveldt revealed who he would be turning to in Nortje's absence.
It came as somewhat of a surprise given that Beuran Hendricks is also in the squad, but on Wednesday the Proteas will almost certainly hand a second ODI cap to Dolphins speedster Daryn Dupavillon.
Langeveldt explained that the 26-year-old Durbanite and Maritzburg College old boy was the most "like for like" replacement for Nortje.
"He has to be our enforcer. He has to do the job of Anrich Nortje. He bowls quite quick and he is a skiddy bowler," Langeveldt said of Dupavillon, who played his one and only ODI against Australia in Potchefstroom over a year ago, where he carded figures of 1/21 (6).
"He brings something different. He has to be a bit more aggressive, especially in the middle period where we need to take wickets.
"He's been brilliant in the nets and he's showed a lot of skill. He's been running in, bowling quick and that's what we're going to ask of him tomorrow, to be able to be our enforcer."
Langeveldt added that the brains trust was also looking at Lutho Sipamla as one of the other replacements, bit confirmed that nothing was finalised yet.
"We haven't made a final decision on the team yet, so we'll wait until we get to the ground in the morning," he said.
While there have been glimpses of what the Proteas can offer with their undeniably talented and diverse attack, Langeveldt was hoping to see more consistency on Wednesday.
"We just have to bowl well. We've started well (in the previous two ODIs) and then they've come hard at our first change bowlers, and that's the thing we need to improve if we want to win World Cups," he said.
"The first change bowlers know their roles and they need to control the run rate. It's not always about taking wickets. We've talked long and hard about it and tomorrow is another opportunity for them to correct it.
"We have to bowl well in the middle period."
Play on Wednesday starts at 10:00.
