Sylhet: Opener Kusal Mendis smashed a career-best 42-ball 70 as Sri Lanka completed a tour sweep, sealing a 75-run win over Bangladesh in the second and final T20 international.
Sri Lanka also claimed the tri-nation one-day trophy and took the Test series 1-0 in their one-and-half-month long Bangladesh tour.
A second straight half-century of the series for Mendis steered Sri Lanka to a hefty 210 -4, before the bowlers put on a fine display to dismiss Bangladesh for 135 in 18.4 overs.

Mendis and Danushka Gunathilaka combined for a 98-run partnership for the opening stand that set up the platform for a big total.
Gunathilaka survived twice on 15 and 28 before he holed out to Tamim Iqbal at long-off for 42.
Thisara Perera joined Mendis to accelerate the innings but Abu Jayed made him his maiden wicket to stall the progress.
However, Shanaka and Upul Tharanga (25) added 63 runs in the last five overs to help the side post a big total.
For Bangladesh, captain Mahmudullah was the sides high scorer with 41 and opener Tamim Iqbal added 29.
