Mathews' third fifty in six follow-ons

3 Number of fifty-plus scores by Angelo Mathews in six innings while following-on in Tests - the most by a Sri Lanka batsman. Before this innings, Mathews had got 63 in Cape Town in 2011-12 and 66 in Christchurch in 2014-15. Mathews has made 234 runs at an average of 46.80 in these innings.

68 Sri Lanka's previous highest sixth-wicket stand while following on in Tests, which was by Mahela Jayawardene and Tillakaratne Dilshan at Lord's in 2006. That match had ended in a draw after Sri Lanka were made to follow on facing a deficit of 359 runs. Dinesh Chandimal and Milinda Siriwardana have added 87 runs in an unbroken partnership in this innings.

311 Runs scored by Sri Lanka at an average of 10.37 in their first three innings of this tour. They have already scored 309 runs for the loss of five wickets in this innings.

2010 Last time England enforced follow-on twice in a Test series before this, which came against Bangladesh in a two-match series. The last such instance by any team was New Zealand against West Indies in 2013-14. This is only the second time Sri Lanka have been asked to follow on in consecutive Tests; the first was against India in 1993-94.

1 Number of lower totals at Chester-le-Street in Tests than Sri Lanka's 101 in the first innings. Zimbabwe were all out for 94 against the hosts in 2003.

128 Balls faced in the partnership between Mathews and Silva - the most by a Sri Lanka pair in this series. Chandimal and Siriwardana have already faced 122 balls in their unbeaten stand of 87 runs. Silva and Dimuth Karunaratne had batted together for 99 balls earlier in the innings which was the previous longest stand in this series by Sri Lanka.

16.9 Kaushal Silva's batting average in his previous ten innings in Tests before his 60 in Sri Lanka's second innings. He had just one fifty in those innings and had failed to score 20 runs in seven of those ten innings. This was Silva's tenth fifty in Tests. He has made 1502 runs at an average of 31.29 in Tests including two hundreds.

100.00 Angelo Mathews' strike rate against Moeen Ali in Sri Lanka's second innings. Mathews carted Moeen for 46 runs including six fours and one six. Mathews finished with a strike rate of 76.19 - his best in an innings of 50 or more runs in Tests.

537 for 9 Sri Lanka's highest total while following on in Tests, which came against England at Lord's in 2006. Their total of 309 for 5 at the end of the third day's play is their fifth-highest while following in Tests. This is also only the second instance after the Lord's Test in 2006 that six of Sri Lanka's top seven scored at least 20 runs in an innings while following on.

0 Number of times Sri Lanka had got all out for less than 125 thrice in a series, before this. This is the first such series for them. Only twice before this they were all out for such a low score two times in a series - against South Africa in 2000-01 and in the home series against Pakistan in 1985-86. In this series, they scored 91 and 119 in the first Test and 101 in the first innings of this second Test.
