South Africa are literally digging in to try and save the fourth and final Test against India.

Chasing a highly improbable target of 481, South Africa stonewalled the opposition with some defensive batting, scoring at just a run an over on a slow strip at the Feroz Shah Kotla ground in New Delhi.

At stumps on the fourth day, the Proteas were 2-72 off 72 overs with skipper Hashim Amla on 23 off 207 balls and AB de Villiers unbeaten on a 91-ball 11.

Amla took 44 balls to get off the mark, and was at one stage on 6 runs from 100 balls.

The top-ranked tourists, who have already lost the series 2-0, will need to bat out three full sessions on the final day to snatch a draw and salvage some pride.

A 300-plus target has been chased successfully just once in a Test match on Indian soil - by the home team which made 4-387 to defeat England in Chennai in 2008.
