Batsman Rassie van der Dussen is in line for his ODI debut and seamer Dane Paterson has been recalled to South Africa's 14-man squad for the first two ODIs against Pakistan to be played later this month. Van der Dussen scored a match-winning fifty on his T20I debut against Zimbabwe last year, but missed out on selection for South Africa's limited overs trip to Australia in November, while Paterson has not played for the Proteas in this format since his debut series against Bangladesh in 2017.
Hashim Amla, who missed the most recent series in Australia while he was recovering from a finger injury, also returns to the squad but JP Duminy and Lungi Ngidi were not considered as their rehabilitation to full fitness continues.
"We need to look at all the options available to us as we get closer to selecting our final squad for this year's World Cup," national selector Linda Zondi said. "Rassie and Dane are two players who have been knocking strongly on the door in all formats."
After his bright T20I debut, van der Dussen continued to make headlines during the inaugural Mzansi Super League, during which he topped the run charts with 469 runs at a strike rate of 138.75 and played a vital role in Jozi Stars' title-winning campaign. Paterson has also been there and thereabouts for a while, having played in the T20Is against Zimbabwe and been included as injury cover in the Test squad against Pakistan.
The trialing of van der Dussen and Paterson means that Farhaan Behardien, Aiden Markram and Chris Morris miss out on the opening exchanges against Pakistan, but they could well get a look-in towards the end of the five-match series, when the squad will be revised.
"Those players who went to Australia and have not been selected for the first two matches - Farhaan Behardien, Aiden Markram and Chris Morris - are by no means out of the picture and they may well get further opportunities in the second half of the series," Zondi said.
"We are very happy with the way in which our Vision 2019 is taking shape. The series against Pakistan could not have come at a better time as they will provide a very stern test for the Proteas under conditions very similar to what we will experience at the World Cup."
