50 - Number of international hundreds for Virat Kohli. He became the eighth batsman overall and second Indian, after Sachin Tendulkar, to get there. Kohli got there in his 348th innings, in Kolkata on Monday, the joint-quickest along with Hashim Amla, who got there in February 2017.
2 - Number of third-innings centuries for Kohli in Tests. Both have come in successive third innings outings against Sri Lanka. The first was an unbeaten 103 in Galle earlier this year. Before these two knocks, Kohli averaged 27.12 in the third innings across 25 knocks, with four half-centuries. The last India captain to score a third-innings century before Kohli was Tendulkar, who did so against New Zealand in Mohali in 1999. The previous India player to score a third-innings century at Eden Gardens was Rahul Dravid, against Pakistan in 2005.
83 - Kohli's run tally across six Test innings at Eden Gardens before this century. He was out for single digits in four of those innings. In ODIs, he has a century and three fifties in six innings here.
119 - Balls taken by Kohli to score this century - his fastest of the 18 Test hundreds. The previous quickest was off 129 balls against New Zealand in Wellington in 2013-14. Kohli scored 68.87% of batsmen runs since he arrived to the crease - 104 out of 151 - at a strike rate of 87.39. While the other batsmen contributed 47 runs at strike rate of 31.92.
9 - Number of hundreds for Kohli across formats this year - three in Tests and six in ODIs - the most by him in any calendar year. He made eight hundreds, his previous best, in 2012 and 2014.
0 - No captain has made more international hundreds in a year than Kohli's nine this year. Ricky Ponting (2005 and 2006) and Graeme Smith (2006) also made nine hundreds. Kohli still has six internationals left this year to set a new record.
1 - Kohli is the first India captain to score a duck and a century in the same Test. He's the 18th captain overall to do so. Last India player to do so was Cheteshwar Pujara, also against Sri Lanka, in Colombo (SSC) in 2015. The last instance of an Indian doing this at home was Dravid, against England in Mohali in 2008.
