CENTURION, South Africa (CMC):Quinton de Kock warmed up for the T20 World Cup by smashing a boundary-studded century to lead South Africa’s superb run chase in a seven-wicket victory over the West Indies here yesterday. It gave South Africa an unassailable 2-0 lead in the three-match series, with the final match to be played tomorrow. Hetmyer, however, continued his rich vein of form, dominating a 126-run partnership with King that put them on course to score 250. Rutherford struck five fours and four sixes in his unbeaten knock, while Shepherd finished on 17 not out off 10 balls. De Kock eventually reached his second T20I century off 43 balls by flicking Holder behind square for six.
