CAPE TOWN (Reuters) - Opener Bhuvneshwar Kumar took a wicket in each of his first three overs as India laid waste to South Africa’s top order on the opening day of the first Test at Newlands on Friday. But a counterattack led by AB de Villiers, who hit a quick fire half century, saw South Africa go to lunch on 107 for three wickets, fighting back on a hot day in an intriguing battle between the top two ranked Test nations. De Villiers was 59 not out after the first session, along with captain Faf du Plessis, unbeaten on 37. Kumar snagged opener Dean Elgar with just the third ball of the day and then in the next two overs had Aiden Markram and Hashim Amla dismissed cheaply to have the home side reeling at 12 for three inside only the fifth over. But de Villiers staged a fight back as he took on Kumar, hitting four 4s off him in an over as he relentlessly punished loose deliveries. De Villiers reached his 50 off just 55 deliveries. Du Plessis was more circumspect at the other end, no doubt also reflecting on his decision to bat after winning the toss before the start of play. His argument that he was going to gamble on batting because the wicket was still soft and would get quicker later in the day as it dried out, looked without substance as Kumar made full use of grass-covered track and had South Africa, who pick four seamers themselves, in early trouble. He had Elgar caught behind by Wriddhiman Saha as he moved the ball away from the left-hander and then Markram leg before for five runs in the third over of the day.
