Sanath Jayasuriya claimed four for 14 as Sri Lanka completed a 3-0 whitewash with a 39-run victory over Bangladesh in the final weather-affected one-day international on Wednesday.
Bangladesh ended a disappointing tour with a fighting performance, bowling out the hosts for 196 in 39.5 overs, but could not prevent another Sri Lanka victory.
Teenage opener Tamim Iqbal kept their victory hopes alive with 54 from 74 balls, adding 42 with Mohammad Ashraful (20) and 60 with Mahmudullah (36).
But Jayasuriya, playing in his 398th game, sealed victory for Sri Lanka by triggering a late collapse to 157 all out as Bangladesh's last five wickets fell for 28 runs.
Paceman Nuwan Kulasekera also struck two vital blows in the middle order, trapping Ashraful lbw and then dismissing Aftab Ahmed courtesy of a spectacular one-handed catch from Kumar Sangakkara.
Earlier, Jehan Mubarak, promoted to number five in a middle-order reshuffle, rescued the Sri Lanka innings with a fine 72 after the hosts had slumped to 61-4 after being put in to bat in the rain-reduced 40-over contest.
