South Africa beat India by four wickets with almost two overs to spare in their second Twenty20 international in Cuttack on Sunday. The Proteas took a 2-0 lead in the five-match series. India were reduced to 98-5 in 13.5 overs before Dinesh Karthik steadied the innings. Only three batters for India crossed 20. Shreyas Iyer said the India vs South Africa series will help India identify the grey areas before the T20 World Cup in Australia later this year. (Video and images: BCCI)
