64 vs South Africa at Cape Town, Test Series 2011
Though it wasn’t a century nonetheless it was a special knock by the southpaw which ensured India saved the Cape Town Test against South Africa during their 2010/11 tour. What made the innings more special was that the southpaw was battling with an injured hand and then got struck while batting but still continued to bat in order to help India salvage a draw.
Chasing an unrealistic victory target of 340 on Day 5, India lost Sehwag early. With victory not within sights, Gambhir decided to drop anchor and battled through pain and batted for around 4 hours to score 64 of 184 deliveries. Though he was dismissed in the end, by then he had made sure India was in a comfortable position to save the Test match.
