Jan 29 (Reuters) - Quinton de Kock ‌smashed a career-best 115 from 49 balls as South Africa easily chased down ‌a victory target of 222 to beat West Indies by seven wickets ‌on Thursday and secure the three-match Twenty20 International series 2-0 with a game to go.

West Indies were sent into bat in Pretoria and amassed 221 for four in their 20 overs, but on an excellent ‍batting wicket South Africa never looked in trouble in ‍their reply and won with 15 ‌deliveries to spare.
