Chandimal and Mathews' Kotla marathon

476- Balls faced by Angelo Mathews and Dinesh Chandimal during their 181-run stand for the fourth wicket. It's the longest partnership between a visiting pair in India in the last five years, and the second-longest stand for Sri Lanka against India. Overall, this is the longest partnership for any pair at the Kotla, trumping the 433 balls Gautam Gambhir and VVS Laxman faced together against Australia in 2008-09.

10- Centuries for Dinesh Chandimal in 80 Test innings: the fastest Sri Lankan to the landmark. The previous quickest was Thilan Samaraweera, who notched up 10 centuries in 82 innings. Kumar Sangakkara took 101 innings for the same.

2- Number of Sri Lanka captains to score a century in India. Before Chandimal, only Sangakkara had done so, at the Brabourne Stadium in 2009-10. Chandimal is the first visiting captain in over 30 years to score a century at Feroz Shah Kotla, after Viv Richards in 1987-88.

36- Number of innings without a century for Mathews before the one in this Test. Mathews averaged only 27.80 in those 36 innings with six fifties. His last ton was also against India, when they visited Sri Lanka in 2015. Between 2014 and 2015, Mathews hit six centuries in 42 innings.

1981- The last instance of two centurions in the same innings for an opposition side at the Kotla. Geoff Boycott and Chris Tavare each made centuries for England then. Chandimal and Mathews' centuries make it the fifth such instance at the Kotla. This is only the second occasion of Sri Lanka having two centurions in an innings in India.

3- Partnerships to have lasted 400 or more balls for Sri Lanka in the last five years; Chandimal has been involved in all three. He partnered Karunaratne against West Indies in Galle in 2015, and with Dhananjaya de Silva against Australia in Colombo (SSC) last year. The last such partnership, before these three, came in 2011.

3- Number of times Chandimal has played innings of 300 or more balls in Tests this year - the highest. Steven Smith, Cheteshwar Pujara and Dimuth Karunaratne have played two such long innings.

2009- Last instance of Sri Lanka's Nos. 4 and 5 both scoring centuries in the same innings, as Chandimal and Mathews did in this match. Mahela Jayawardene and Samaraweera had done it in Galle then.
