Dec 9 (Reuters) - India beat South Africa by 101 runs in the first T20 International on Tuesday in Cuttack after the visitors were bowled out for their lowest total in the format following Hardik Pandya's heroics with the bat.

Pandya marked his return to the national team from a two-month injury layoff with a quick-fire fifty before picking up one wicket, walking in with India reeling at 78-4.
