Keshav Maharaj and Kagiso Rabada combined on Saturday to earn South Africa a healthy first innings lead over the West Indies with the visitors attempting to defy the impact of inclement weather in seeking to force an unlikely victory going into the final day of the first Test of a two-match series in Trinidad.
Steady rain restricted play to just the final session on the fourth day but in that time South Africa dismissed the home side for 233 in the first innings and then made their intentions clear in reaching 30 without loss off five overs in the second innings at the close.
With an overall lead of 154 runs and all ten wickets in hand, the Proteas will be hoping for a full day's play on Sunday for their batsmen to try and at least lay the platform which will give the bowlers a chance to put the Caribbean side under pressure in the final innings of this truncated match.
