Bangladesh restricted Sri Lanka to 132 for seven in the third T20I of the three-match series on Wednesday.
Mahedi Hasan bagged four wickets. He was playing replacing Mehidy Hasan Miraz.
After winning the toss and opting to bat, Sri Lanka struggled to build momentum on a slow surface. Despite a steady start from opener Pathum Nissanka, who top-scored with 46 off 39 balls, the hosts kept losing wickets at regular intervals.
Bangladesh bagged two wickets early— in the first two overs of the match.
Nissanka lacked support from the other end as Kusal Perera, Dinesh Chandimal, and captain Charith Asalanka all fell cheaply.
Sri Lanka bat first in final T20I, lose two quick wickets
Mahedi was the standout performer for Bangladesh, returning remarkable figures of 4 for 11 in his four overs, including a maiden. He removed four of Sri Lanka’s top five batters, breaking the backbone of the innings.
Kamindu Mendis (21 off 15) and Dasun Shanaka (35* off 25) tried to rebuild in the middle overs, but the lack of partnerships hurt the home side.
Mustafizur Rahman bowled tightly at the death and claimed one wicket for just 17 runs, while Shamim Hossain chipped in with a key scalp.
Sri Lanka managed only 38 runs in the final five overs, finishing with a modest 132 for 7—well below par on a surface where 160-plus has been a competitive total in the series.
Shoriful Islam leaked 50 runs in four overs. In the last over, he conceded 22 runs.
