Ireland women's team beat Bangladesh by 47 runs in the second T20 international on Saturday (Dec 7) to secure an unassailable 2-0 lead in the series.
The visitors made 134-5 off their 20 overs in Sylhet, with Laura Delany top-scoring with 35 and Orla Prendergast adding 32.
The Tigresses were 87 all out after 17.1 overs in reply, with Prendergast completing a fine individual performance by claiming three wickets for 13.
The final match will take place on Monday at the same venue.
Prior to the T20I encounters, Ireland lost the ODI series 3-0 in Dhaka.
Openers Gaby Lewis and Amy Hunter put on 34 for the first Ireland wicket, with Lewis first to fall for 14 in the sixth over.
Hunter was out for 23 in the ninth but Prendergast's contribution off 25 balls and Delany's impressive knock helped the tourists to a healthy total.
Nahida Akter was the pick of the home bowlers with 2-20.
Wickets fell regularly during the Bangledash response, with only middle order batters Sharmin Akter Supta (38) and Shorna Akter (20) putting up significant resistance. The pair combined for a fifth-wicket partnership of 48 but by then their side's hopes of victory were already hanging by a thread.
The hosts' final three wickets fell within the space of four balls as Ireland triumphed with something to spare.
In addition to Prendergast's three-wicket haul, Arlene Kelly and Delany took two wickets apiece.
