The second string Bangladesh side, which drew the three-match four-day series 1-1, had confirmed their one-day series victory by winning the first three games but suffered a six-wicket loss in the fourth game.

An all-round performance by Sakib Al Hasan -- who got a senior team call-up for the upcoming Zimbabwe and Kenya tours -- powered the visitors to win the series 4-1, the left-handed batsman scoring unbeaten 55 before claiming four wickets for 44 with his left-arm spin.

Tushar Imran led from the front with team highest 66 as the tourists piled up a towering 331 for six in the stipulated 50 overs in the tour finale. Nafees Iqbal contributed 54 runs while another young southpaw Mehrab Hossain Jr contributed an unbeaten 38.

Piet Rinke hit 107 but it was not good enough for the home side to topple the huge total as they were restricted to 273 for eight in allotted 50 overs.

The Bangladesh team are expected to return home on Sunday.
