The pink-ball preparations step up a notch on Saturday when the Proteas take on a Cricket Australia XI in a two-day tour match at the Adelaide Oval.
The Proteas are considering returning to the old days and fielding an all-pace attack in perhaps two of the three Tests in Australia.
Australia have lost 5-0 for the first time ever in an ODI series, after the Proteas beat them by 31 runs at Newlands on Wednesday.
The Aussies say they will not back down from sledging despite Tabraiz Shamsi and Matthew Wade being fined for their fourth ODI confrontation.
The Proteas have gone 4-0 up in the series after a comfortable six-wicket victory against Australia at St George’s Park on Sunday.
