Aiden Markram, who scored 94 on Day 1 of the second Test match between India and South Africa in Centurion, praised Ravichandran Ashwin and called him a 'world class' bowler. The hosts were off to a brilliant start, but Ashwin's three wickets brought them back into the game. Ashwin took 3/90, accounting for Markram, Dean Elgar and Quinton de Kock. (Video Courtesy: SNTV)
