The series heads into the final match locked at 2-2 in what has been a hard-fought contest between the Windies and the Proteas.
With the surface deteriorating, it seems that a score of more than 165 is enough to win most matches, with no side able to break 170 and a total of 167 being defended in successive games.

To Win Match
West Indies 67/100
South Africa 5/4
The West Indies lost the toss for the first time in the series in match four, but it worked out in their favour as the Proteas faltered under pressure in the chase.
Thanks to their best bowling performance, the hosts have kept the series alive heading into the final match of the tour.
Skipper Kieron Pollard led from the front with a superb all-round performance while he also held back Fabian Allen from bowling in a smart move, while using Chris Gayle to make get some overs in early and prevent the tourists getting off to a great start.
Openers Lendl Simmons and Evin Lewis have both looked dangerous throughout the series, and if they can fire together it will give the West Indies a real edge.
For the Proteas, the batting failure followed an all-too-familiar pattern with Quinton de Kock carrying their effort, not just in the fourth T20I but throughout the series.
Tabraiz Shamsi has been consistent with the ball in hand and most of the Proteas bowlers have been close to their best.
The batting problems must be solved if South Africa are to mount any sort of challenge at the T20 World Cup which will now be held in Oman and the UAE.
Despite their struggles, South Africa have a shot at winning a T20I series on foreign soil since 2015.
Verdict: West Indies 67/100
The Windies were expected to win this series and will be determined to get it done.
