Mustafizur Rahman and Soumya Sarkar shone as Bangladesh thumped Ireland by eight wickets in their latest one-day international tri-series fixture at Malahide.

Both teams came into Friday's contest seeking their first victory in a series that also features New Zealand, but Ireland's hopes of getting off the mark were significantly dented as they slumped to 181 all out after being put in to bat.

Seamer Mustafizur was chiefly responsible for the hosts' poor showing, returning 4-23 from nine overs, while there were two wickets apiece for skipper Mashrafe Mortaza and debutant spinner Sunzamul Islam.

Bangladesh then cantered to their target with 22.5 overs to spare, Sarkar underpinning the successful chase with 87 not out from 68 deliveries - an innings featuring 11 fours and two sixes.

Sarkar, who was given a life on 57, shared 95 for the first wicket with Tamim Iqbal (47) and a further 76 with Sabbir Rahman (35) as Bangladesh cruised to victory.

Having been put in to bat, Ireland got off to a poor start as the dangerous Paul Stirling fell to Mustafizur for a duck in the second over.

Bangladesh's young seamer also accounted for Niall O'Brien, Kevin O'Brien and Gary Wilson to leave Ireland reeling on 136-7, despite 46 at the top of the order from Ed Joyce.

It was Sunzamul who brought Joyce's innings to an end and the left-armer went on to dismiss Barry McCarthy for his second scalp before Mashrafe brought the innings to a close with two wickets in the 47th over.

Sarkar and Tamim soon had Bangladesh firmly on course in reply and victory for the visitors never looked in doubt.
