South Africa wicket-keeper batsman, Quinton de Kock, bagged the record of the fastest half-century in T20I cricket for a Proteas player to his name as he scored 50 in just 17 balls. He hit a 22-ball 65 against England in the second T20I of the series. While the effort is quickest for a South African, De Kock finds himself joint 6th in the overall list which is led by India's Yuvraj Singh who had scored a 12-ball 50 against England in the 2007 World T20.
