Virat Kohli slammed an unbeaten half century and took a stunning catch to lead from the front as India eased to a seven-wicket win over South Africa in the second T20 international here on Wednesday. Skipper Kohli first took a brilliant catch running to his left from mid-off off Navdeep Saini’s bowling in the 12th over to send counterpart Quinton de Kock (52 off 37 balls; 8×4) back in the hut and stymie South Africa’s run-flow as they ended up with 149/5 in 20 overs after being asked to bat first.
