Visakhapatnam: Mayank Agarwal completed his maiden Test hundred while Rohit Sharma made 176 on his opening debut as India headed towards a huge first innings total at lunch on day two of the series opener against South Africa here on Thursday. Rohit, who hit 23 fours and half a dozen sixes, was eventually dismissed in the 83rd over. At lunch India were 324 for one in 88 overs with Agarwal going strong at 138 off 270 balls.

The hosts scored 122 runs in the session at 4.28 runs per over. Rohit and Agarwal, who resumed their innings at 115 and 84 respectively with India at 202 for no loss, did not take long to register India's highest opening stand against South Africa, surpassing the 218 made by Gautam Gambhir and Virender Sehwag at Kanpur in 2004. A little later, when the duo crossed the 268-run mark, their stand became the highest against the Proteas for any wicket, surpassing Rahul Dravid and Sehwag's effort in 2007-08.
