KOLKATA, India (Reuters) -Off-spinner Simon Harmer led South Africa's lion-hearted bowling effort as the Proteas registered a thrilling 30-run victory against India inside three days of the low-scoring opening test on Sunday.

Harmer claimed 4-21 as India, chasing 124 for victory, folded for 93 in a remarkable batting meltdown in front of the nearly 40,000-strong crowd at Eden Gardens.
