After being sent in to bat under heavy skies, South Africa laboured to 29 for two from 7.3 overs before persistent rain throughout the day ensured there would be no more play.
Before the persistent rain settled, Quinton de Kock was not-out on 17 and Faf du Plessis on 0 after just seven balls faced.
For much of this final, rarely, if ever, has any opponent played so well against Nadal on this Philippe Chatrier centre court.
