On Thursday, Gill -- aged 19 years 334 days -- scored a brilliant double century against West Indies A in the third unofficial Test at Brian Lara Stadium, breaking the previous record held by Gautam Gambhir, who had scored a double-century for India's Board President XI's team against Zimbabweans in 2002.
Gambhir was 20 years and 124 days old when he had become the youngest Indian cricketer to score a double century in first-class cricket.
Gill made up for his first-ball duck in the first innings as he struck an unbeaten 204 while skipper Hanuma Vihari came up with an important knock of 118 not-out as they led a remarkable comeback after India A were in deep trouble having suffered a top-order collapse.
During the course of his 250-ball innings, Gill scored at a strike rate of over 80, and hit 19 fours and 2 sixes.
India A declared their innings at 365 for 4 to set a target of 373 for West Indies A. At the end of day three, the hosts were 37 for no loss and need 336 more to win the match.
