KANDY (Reuters) - Tillakaratne Dilshan's 17th one-day century proved in vain on Thursday as Bangladesh beat Sri Lanka by three wickets under the Duckworth/Lewis rain rule to win the third and final one-day international and share the series one-all. Sri Lanka looked to be in control when they ran up an impressive 302 for nine after choosing to bat first. But Bangladesh whose run chase was interrupted in the 14th over when they were 78-1, were then set a revised target of 183 to win off 27 overs.

Sri Lanka scored a challenging 302-9 after electing to bat against Bangladesh in the third and final one-day international in Pallekele on Thursday. Opener Tillakaratne Dilshan top-scored for Sri Lanka with a solid 125, while Kusal Perera (56) and Kumar Sangakkara (48) were the other main scorers in the day-night match. Bangladesh's left-arm spinner Abdur Razzak finished with 5-62 off 10 overs. Sri Lanka lead 1-0 in the series following their eight-wicket win in the opening match in Hambantota. The second one-dayer at the same venue was abandoned due to rain.

Tillakaratne Dilshan hammered an unbeaten 113 to fire Sri Lanka to an eight-wicket win over Bangladesh in the first one-dayer, marked by a power failure and bees' invasion on Saturday. The opener hit 11 fours in his 15th one-day century as Sri Lanka, chasing a revised target of 238 in 41 overs following the outage, won the day-night match in Hambantota with 32 balls to spare for a 1-0 lead in the three-match series.

Rangana Herath celebrated his 35th birthday with a career-best 7-89 as Sri Lanka clinched the series against Bangladesh with a comfortable seven-wicket win in the second and final Test on Tuesday. Opener Tillakaratne Dilshan (57) and left-hander Kumar Sangakkara (55) put on 94 for the second wicket to steer the home team towards their 160-run target on the penultimate day in Colombo. The opening Test in Galle ended in a draw.
