Sarkar's rare three-in-a-row
64 Test innings taken by Dinesh Chandimal to make eight Test hundreds - the second fastest by a Sri Lanka batsman. Mahela Jayawardene had taken ten fewer innings than Chandimal to get his first eight hundreds. Thilan Samaraweera is next on this list having made his eighth Test hundred in his 74th innings.
4 Number of hundreds by Chandimal against Bangladesh in just eight Test innings. Only three other batsmen - Kumar Sangakkara (7), Mahela Jayawardene (5) and Sachin Tendulkar (5) - have hit more hundreds against them. Shivnarine Chanderpaul and Tillakaratne Dilshan too have hit four Test hundreds against Bangladesh. Chandimal has made 578 runs against Bangladesh at an average of 115.60.
2010 Previous instance of an overseas opener getting three or more fifty-plus scores in a Test series in Sri Lanka. Virender Sehwag had scored two hundreds and a fifty in the three-match series on that occasion. Overall, Soumya Sarkar is only fifth visiting opener to get three fifty-plus scores in a series in Sri Lanka.
1 Number of Bangladesh openers before Soumya Sarkar to get three fifty-plus scores in a Test series. Tamim has done it thrice: against Zimbabwe in 2014-15, and twice against England, in 2009-10 at home and in 2010 in England.
4 Number of Bangladesh batsmen before Sarkar to make three or more consecutive fifty-plus scores in Tests. Habibul Bashar, Tamim Iqbal, Mushfiqur Rahim and Nasir Hossain are the batsmen to do so. While Tamim has had a streak of five consecutive fifty-plus scores, Bashar had three separate such streaks in Tests.
2010 Previous instance of an opening pair adding three or more fifty-plus stands in a Test series in Sri Lanka. Tillakaratne Dilshan and Tharanga Paranavitana had added four such stands against India on that occasion. Tamim Iqbal and Soumya Sarkar have added 118, 67 and 95 in this series so far. Tamim and Sarkar are only the third Bangladesh opening pair to make three consecutive fifty-plus stands in Tests. Tamim and Imrul Kayes have done it twice. Javed Omar and Nafees Iqbal are the other pair to do it.
143 Runs added by Sri Lanka's last-three wickets - which amounted to 42.3% of their first-innings total. This is the second-highest percentage of runs added by Sri Lanka's last-three wickets when they have put up a total of 300 or more. Their last-three wickets had added 207 runs out of a total of 486 in Galle against South Africa in 2004 - a contribution of 42.6% to the team total, which is the highest.
0 Number of fifty partnerships by Sri Lanka for their ninth-wicket in Tests against Bangladesh before the one between Suranga Lakmal and Chandimal. Sri Lanka have added more runs for their ninth or tenth wickets in a Test innings against Bangladesh only once before this. Charitha Buddhika and Chamila Gamage had added 64 runs for the tenth wicket at the SSC in 2002.
3 Wickets Bangladesh lost in the space of seven deliveries in the last half hour of play on the second day. They lost two settled batsmen in Imrul Kayes and Sabbir Rahman, and the nightwatchman Taijul Islam, who was sent in ahead of Shakib Al Hasan. Before that run of play, Bangladesh had progressed to 192 for 2 - their fourth-highest score in away innings before the fall of their third wicket. This was the highest they had made before the fall of their third wicket in an away Test since the second innings of the Lord's Test in 2010.
