Halfway through the 37th over of South Africa's tense chase in the second ODI in Durban, Phehlukwayo inside-edged a Shaheen Afridi delivery to deep fine leg for a single. He was on 50 at the time and as he ran off to the non-striker's end, Sarfraz was caught clearly on the stump mics saying, in Urdu: "Abey kaale, teri ammi aaj kahaan baitheen hain? Kya parwa ke aaye hai aaj?".
Translated literally that is: "Hey black guy, where's your mother sitting today? What [prayer] have you got her to say for you today?"
On commentary, Mike Haysman asked Ramiz Raja, "What's he saying there Ramiz?"
"Difficult really to translate that," Ramiz replied. "It's a big long sentence."
Phehlukwayo had enjoyed considerable fortune through the innings, not least when successfully reviewing an on-field lbw dismissal and a dropped catch in the over before this incident. Pakistan's players had come hard at him early on, though in the post-match presentation he said, "it was good chat".
*"The ICC and the match officials have noted the alleged incident. They have started the necessary procedures to investigate the matter. We can only comment once we have received the results of the investigation. Any further clarification/updates have to go through the ICC," said Mohammed Moosajee, the South Africa team manager.
Any disciplinary action can be instigated by the match officials. Potentially, if action is to be taken, it will be up to the match officials to decide whether they view Sarfraz's comments under the ICC code of conduct for player behaviour or the ICC's anti-racism code. Article 2.13 of the regular code covers the use of insulting or obscene and offensive language used by players against another in the regular code of conduct. But it says: "This offence is not intended to cover any use of language that is likely to offend another person on the basis of their race, religion, gender, colour, descent, national or ethnic origin.
"Such conduct is prohibited under the ICC's Anti-Racism Code and must be dealt with according to the procedures set out therein."
In the Anti-Racism code, in place since October 2012, an offence is described as "any conduct (whether through the use of language, gestures or otherwise) which is likely to offend, insult, humiliate, intimidate, threaten, disparage or vilify any reasonable person in the position of a Player, Player Support Personnel, Umpire, Match Referee, Umpire Support Personnel or any other person (including a spectator) on the basis of their race, religion, culture, colour, descent, national or ethnic origin."
Phehlukwayo had a memorable day in any case, his unbeaten 69 part of an unbroken 127-run stand that steered South Africa home after they had wobbled to 80 for 5. And earlier in the day his 4 for 22, including the crucial wicket of Sarfraz, helped bowl Pakistan out for 203.
