Stumps Sri Lanka 39 for 2 (Karunaratne 18*, O Fernando 19, Taijul 1-1) and 397 trail Bangladesh 465 for 9 dec (Tamim 133, Mushfiqur 105, Litton 88, Mahmudul 58, Rajitha 4-60, Asitha 3-72) by 29 runs

If day three of the first Test in Chattogram belonged to Tamim Iqbal, the fourth day was all about Mushfiqur Rahim. Not only did he become the first Bangladesh batter to reach 5000 runs in Test cricket, his eighth century in the format also made sure Bangladesh stayed ahead in Chattogram at the end of day four.

Mushfiqur's 105, to go with Tamim Iqbal's 133, and half-centuries from Litton Das and Mahmudul Hasan Joy helped Bangladesh declare their first innings on 465 for 9, and secure a lead of 68 runs in reply to Sri Lanka's first innings score of 397.

Dimuth Karunaratne and Oshada Fernando then started their second innings steadily before the latter was run out needlessly for 19. Lasith Embuldeniya, the nightwatchman, had a few nervy moments but did his job before being bowled off the final ball of the day by Taijul Islam. At stumps, Sri Lanka had reached 39 for 2, still trailing Bangladesh by 29 runs. Karunaratne was unbeaten on 18, and will be joined by Kusal Mendis, in all likelihood, tomorrow morning.

The start of the day started was delayed by 30 minutes because of rain but once play resumed, it did not take long for Mushfiqur to reach the 5000-run mark. He began the day just 15 runs away from the landmark and breached the milestone with a deflection off his gloves down to fine leg shortly after the first drinks break. Adopting a cautious approach, Mushfiqur surged ahead and soon reached his century after lunch, his first in Test cricket in more than a year.

Bangladesh resumed their day on 318 for 3, with Litton and Mushfiqur picking up from where they had left on the third evening. Both batters were cautious but made sure no wickets were lost as Bangladesh reached 385 for 3 at lunch. The Sri Lankan bowlers, much like the third evening, lacked the bite and could not get much out of the surface.

However, the visitors came back well in the second session. Rajitha struck straight after lunch, first removing Litton before uprooting Tamim's middle stump the very next ball. Litton, in particular, would be kicking himself for missing a third Test hundred after edging an innocuous short and wide first ball after lunch to the wicketkeeper. The ball to Tamim, though, was a good one. Coming back to bat after retiring hurt at tea on the third day, Tamim went for the expansive drive to a fuller delivery. However, Rajitha, bowling from around the wicket, got the ball to angle in and it crept between Tamim's bat and pad to hit the middle stump.

Shakib, having survived a close chance at short leg, was rattled by a bouncer barrage from Asitha Fernando. He was hit by the pacer on the helmet, and soon after was dismissed going for the pull shot for 26.

Mushfiqur, meanwhile, held his own at the other end even as things started heating up in the middle. There were a few glares and words exchanged with Asitha, but the batter remained firm. He reached his century with a faint tickle off Asitha down the leg side and celebrated wildly.

Mushfiqur's 282-ball vigil finally ended after tea, when looking to play the sweep against Embuldeniya, he missed the line and found his stumps in a mess. Taijul Islam and Shoriful frustrated the Sri Lankans with a 26-run stand before Asitha sent Taijul back. Bangladesh declared their innings on 465 for 9 after Shoriful, struck on the hand by a bouncer, retired hurt.

Sri Lanka toiled away and bowled well in patches, particularly in the middle session on both the third and fourth days. However, a couple of wicketless sessions cost them. Rajitha, who was not even part of the playing XI and came in as a concussion sub for Vishwa Fernando, was the pick of the bowlers, finishing with 4 for 60.

Sri Lanka started their second innings well with both Karunratne and Oshada looking comfortable. However, a direct hit at the bowler's end from Taijul sent Oshada packing. Karunaratne also had an escape when he mistimed a drive back to Nayeem Hasan, but replays showed the ball had just fallen short of the bowler.

Embuldeniya gave Karunaratne good support, but the surface started to show tricks late in the day with the odd-ball staying low. How Sri Lanka survive the final day remains to be seen.
