Harshitha Samarawickrama made a composed half-century to guide Sri Lanka to a seven-wicket win over Bangladesh at Newlands in Cape Town on Sunday for their second successive victory at the Women's T20 World Cup.

Left-handed opening batter Harshitha made 69 not out and shared an unbeaten 105-run partnership with Nilakshi de Silva (41 not out). 

They enabled Sri Lanka to survive an early scare in pursuit of a modest Bangladesh total of 126 for eight.

Sri Lanka, who beat hosts South Africa in the tournament opener on the same pitch on Friday, were rattled when 18-year-old medium-pace bowler Marufa Akter took three wickets without conceding a run to reduce them to 25 for three in the sixth over.

Akter, whose previous five international matches had yielded only three wickets, struck with her third delivery when she had Sri Lanka captain Chamari Athapaththu caught at midwicket. 

In her next over she dismissed Vishmi Gunarathne and Anushka Sanjeewani with successive deliveries.

Harshitha and De Silva had to rebuild on a pitch of uneven bounce and they took the total to 49 after 10 overs, increasing the tempo as Bangladesh were unable to make any further breakthroughs.

Bangladesh lost five wickets for 24 runs in the closing stages of their innings.

Shamima Sultana (20), Sobhana Mostary (29) and captain Nigar Sultana (28) all scored briskly but the innings crumbled after the skipper was caught at midwicket off off-spinner Oshadi Ranasinghe in the 16th over.
