Rangana Herath returned career—best match figures of 12-157 to propel Sri Lanka to a seven-wicket win against Bangladesh on the fourth day of the second test and seal a 1-0 series victory.
Chasing 160 to win on Tuesday, Sri Lanka reached the target losing three wickets in the final session, led by Tillakaratne Dilshan (57) and Kumar Sangakkara (55).
Seamer Robiul Islam took the wickets of both openers Dimuth Karunaratne and Dilshan.
Dilshan hit six boundaries off 73 deliveries and shared 94 for the second wicket with Sangakkara, who faced 85 deliveries and hit eight boundaries.
Earlier, Herath took 7-89 to help dismiss Bangladesh in its second innings for 265. He picked up four of the six wickets that fell on Tuesday morning. It was his best bowling figures in an innings, and this was the third time he has achieved 10 wickets or more in a test improving on his 12-171 against England at Galle last year. The performance also took him to 200 test wickets in his 47th match.
Resuming day four at 158-4, Bangladesh lost Mominul Haque for 37 with just one run added to his overnight score. Herath kept up the pressure by bowling Nasir Hossain for a duck.
Captain Mushfiqur Rahim and Sohag Gazi resisted briefly with a promising 31-run stand for the seventh wicket but Gazi was out for 26 to an ambitious shot against Herath, caught by Suranga Lakmal in the deep.
Rahim soon followed after being caught at slip by his opposing captain Angelo Mathews. Rahim made 40 off 87 deliveries which included three boundaries and a six. Tamim Iqbal was the top-scorer for Bangladesh with 59 runs.
Sri Lanka dismissed Bangladesh for 240 in the first innings and scored 346 to set up a 106-run first-innings lead.
The first test had ended in a high-scoring draw last week.
