Sri Lanka 531 and 102 for 6 (Mathews 39*, Madushka 34, Mahmud 4-52) lead Bangladesh 178 (Zakir 54, Asitha 4-34, Kumara 2-19) by 455 runs

It was also their fifth successive sub-200 score in Tests, as their batting crumbled on either side of the lunch break on the third day.

Sri Lanka had a few whiffs of a wicket but Zakir and Taijul kept them at bay for an hour and 19 minutes in the morning session. That changed spectacularly when Vishwa burst an inswinger through Zakir sending the leg-stump for a cartwheel. Soon after, Prabath got Najmul Hossain Shanto to chip one to short midwicket.

Bangladesh lost a third wicket in three overs when the left-arm quick Vishwa got another of his fast in-duckers ripping through Taijul's defences. The nightwatcher, sent in at No. 3 on the second evening, resisted for an impressive 61 balls.

Sri Lanka continued the pressure after lunch when Asitha set up Shakib Al Hasan with a two-card trick. After bowling a series of short balls, he surprised the left-hander with a full ball that struck his front pad plumb. Shakib in his first Test innings in almost 12 months fell for 15.

Three balls later, Asitha removed Litton Das. The wicketkeeper-batter, under fire for his careless shot in Sylhet last week, struck a nice cover drive before edging a straight, slightly wide delivery from Asitha. Kumara then got Shahadat Hossain to edge one to second slip.

Sri Lanka dropped two catches around this time, while Mominul Haque became the fourth Bangladeshi batter to reach 4,000 Test runs. The experienced left-hander batted confidently on the ground where he has seven Test centuries. But Asitha's yorker resulted in his lbw dismissal, for 33. Khaled Ahmed fell in Asitha's next over, another yorker, giving the fast bowler his fourth wicket of the innings.

The pacers' domination continued in Chattogram when Mahmud and Khaled rocked Sri Lanka with six wickets.

Dimuth Karunaratne and Kusal Mendis were cleaned up by Mahmud and Khaled respectively. Mahmud then removed Nishan Madushka, Dinesh Chandimal and Dhananjaya in consecutive overs in his second spell.

Madushka struck one to extra cover while Shahadat Hossain finally caught one in the slips, removing Chandimal for 9. De Silva was caught behind for 1, as Mahmud was rewarded for his off-stump channel consistency.

Khaled rounded up the day with Kamindu Mendis' wicket, edging one behind the wicket for 9. Captain Shanto took the timely review which showed the edge. Bangladesh's fielders enjoyed the wickets; at one stage, five fielders from the slip cordon chased an edge to the boundary much to the tiny crowd's glee. The players walked off slightly happier than earlier in the day although they have a mountain to climb in the fourth innings.
