Markram, who is again leading the team in the absence of ill Temba Bavuma, said he was hopeful of having the regular captain back for the Proteas’ next match against Pakistan in Chennai on Friday.
“He’s improved a lot but he wasn’t quite ready for today. Hopefully he will keep improving and be ready for Pakistan.
