1960 The last time an opening pair put on a higher stand in the second innings than the currently unbeaten 273 between Imrul Kayes and Tamim Iqbal. Colin Cowdrey and Geoff Pullar had added 290 against South Africa. Andrew Strauss and Marcus Trescothick had also added 273 runs against South Africa in Durban in 2004.

267 Bangladesh's previous best partnership for any wicket, courtesy Mohammad Ashraful and Mushfiqur Rahim against Sri Lanka in Galle in 2013. Imrul and Tamim have broken that record and have put up only the fifth double-century partnership for Bangladesh.

0 Bangladesh batsmen to make hundreds in three consecutive Tests before Tamim. He had made centuries against Zimbabwe in back-to-back Tests last year. He has seven Test hundreds now, which is the most by any Bangladesh batsman.

7 times that Bangladesh openers have made fifty-plus scores in both innings of a Test before Imrul in this match. This is the first time in 12 years that a Bangladesh opener other than Tamim has done this. Hannan Sarkar had hit 76 and 55 against Australia in 2003. The five instances since have come from Tamim.

0 Double-century opening partnerships against Pakistan in the second innings before this one. The highest any pair had added was 192, by Chetan Chauhan and Sunil Gavaskar in the Lahore Test in 1978.

277* The highest partnership for any wicket against Pakistan in the second innings, by Andy Flower and Murray Goodwin in Bulawayo in 1998. This unbeaten stand between Imrul and Tamim is now only five runs short of bettering that record. It is also only the second time Pakistan have conceded 250-plus runs to any second-innings partnership.

1 Double-century partnerships by Bangladesh's openers in Tests before today. Imrul and Tamim were responsible for that as well, when they added 224 against Zimbabwe in Chittagong last year. Their unbeaten stand of 273 is now Bangladesh's highest for the first wicket in Tests. Bangladesh's previous best opening stand in second innings was also between the same pair, when they put on 185 runs against England at Lord's in 2010.

1 Time that both of Bangladesh's openers have made hundreds in an innings before this Test. It was Imrul and Tamim again against Zimbabwe in Chittagong last year. This is the 13th time in Tests that both openers have scored centuries in the second innings, and the first time it has been achieved against Pakistan.

367 Balls faced by Anshuman Gaekwad and Sunil Gavaskar in Bangalore in 1983 - the most by an opening pair against Pakistan in the second innings. Imrul and Tamim have already reached 366.

2000 The last time Pakistan posted a total in excess of 600 runs in an away Test before their first innings in this match. They had declared at 600 for 8 against Sri Lanka in Galle. This is only the eighth time they have notched up a 600-plus total outside Pakistan in Tests.

3 Five-wicket hauls by Taijul Islam, who is playing only his sixth Test. He is the third Bangladesh bowler to take three-five fors in his first six matches. Enamul Haque Jnr and Mohammad Rafique were the other two. Taijul's 6 for 163 is Bangladesh's second-best innings haul against Pakistan in Tests after Shakib Al Hasan's 6 for 82 in Dhaka in 2011.

31 Wickets taken by Taijul in his first six Tests - five more than the most taken by any Bangladesh bowler. He went past Mohammad Rafique and Sohag Gazi's tally of 26, and still has an innings left to bowl in the Khulna Test.

27.16 Runs conceded per wicket by Taijul in Pakistan's first innings. This is the third-highest average for a Bangladesh bowler while taking a five-wicket haul. Rubel Hossain averaged 33.20 per wicket when he took 5 for 166 against New Zealand in the Hamilton Test in 2010.
