137 vs New Zealand at Napier, Test Series 2009
Undoubtedly the innings at Napier will remain one of the most special innings by Gambhir just due to the remarkable patience shown by the southpaw in order to ensure that India still maintained their 1-0 lead in the series.
New Zealand scored a mammoth 619 in the 1st innings and India responded with a below par 305. Kiwis skipper Daniel Vettori enforced the follow on. Gambhir lost his opening partner Sehwag quickly but stitched together vital partnerships with Rahul Dravid and Sachin Tendulkar to take India towards safety.
In the process, Gambhir also struck some delightful shots but what stood out was his perseverance. He was eventually dismissed on 137 of 436 deliveries. His innings lasted an incredible 643 minutes and ensured India eventually on the series 2-1.
