A grand finale will close the first series of West Indies’ home summer and they will be itching for silverware, especially after losing the Test series 2-0.West Indies have held the lead, then fallen behind and then drawn level to lock this five-match series at 2-2, and create the kind of pressure South African teams (and their opposition) dream of.South Africa have lost eight out of the 10 deciders they have played in, only beating New Zealand home and away in 2012. Can they take a turn for the better here?
