Basseterre: Barbados Royals 162-7, St Lucia Kings 91-4 - Barbados Royals win by 11 runs (DLS)
A four-wicket burst from Kyle Mayers with the new ball earned Barbados Royals victory over St Lucia Kings, either side of the latest rain delays to impact the weekend's Caribbean Premier League action.
At one stage, it looked as though St Lucia might escape with a point despite being reduced to 7 for 4 inside three overs by Mayers' medium pace. Rain came at the end of the fourth over, with six more balls required to constitute a game.
The weather eventually relented in time for a nine-over chase to be set up, though that was effectively an exercise in completing victory for Barbados, whose early wickets meant that Kings would need to chase 103 in nine overs, but beginning at 10 for 4 with only five overs remaining.
Faf du Plessis and Alzarri Joseph made a fair fist of the situation, bringing the equation down to 55 in three overs but ultimately fell short of an unlikely recovery win.

Quinton de Kock made 24, batting in the unusual position of No.3, before compatriot David Miller contributed the same score and both Jason Holder and Joshua Bishop added late runs to take Barbados to 162 for 7, which seemed a useful score on a surface that became tougher for batting.
Mark Deyal claimed the wickets of de Kock and Corbin Bosch, ending with figures of 2 for 15. Joseph and Scott Kuggeleijn also picked up two apiece.
Du Plessis and Joseph came close to a remarkable turnaround, with Bishop and Holder conceding 20 runs apiece from their two overs. Ramon Simmonds' solitary cost 12 and Obed McCoy's 13, but Bosch successfully defended 30 in the last over, even if du Plessis and Joseph managed 18.
