DHAKA — Suranga Lakmal led Sri Lankan bowlers on a confidence-boosting rampage to skittle out Bangladesh for 82 on Thursday and guide his side into the final of the Dhaka tri-nation tournament. Openers Upul Tharanga (39) and Danushka Gunathilaka (35) sped to the target 83 in just 11.5 overs to seal the win for the islanders. This is what we're capable of, said Sri Lankan captain Dinesh Chandimal as he celebrated the emphatic 10-wicket win that left Zimbabwe in third place in the series and ensured Sri Lanka another match against Bangladesh in Saturday's final.
