Chennai: Skipper Stefanie Taylor and Hayley Matthews starred with both bat and ball as the West Indies brushed aside Bangladesh by 49 runs in a Group B match of the ICC Women's World Twenty20 in Chennai on Sunday.

In a Group A match in Mohali, Sri Lanka defeated Ireland by 14 runs to record its first win in the tournament. Both teams had lost to New Zealand in their opening games.

Taylor scored 40 and Matthews made 41, sharing an opening stand of 67, as the West Indies hit up 148 for four after electing to take first strike.

Taylor then picked up three for 13, supported by two wickets each from Matthews and Deandra Dottin, as Bangladesh were shot out for 99. Nigar Sultana top-scored with 27.

The West Indies climbed to the top of Group B with its second consecutive win, having defeated Pakistan by four runs in the first match.

Bangladesh suffered its third successive loss in the tournament, knocking the South Asian nation out of the race for the semi-finals. It was Bangladesh's 21st defeat in 23 T20 internationals.

"We batted deep in the innings and it was nice of Hayley and me to get a good opening stand that helped us put up a decent total on the board," said Taylor.

"We still need to work on our fielding, it is not one of the best. But I am happy the way we bowled and put Bangladesh under pressure."

The West Indies next plays strong contender England in Dharamsala on Thursday, a match that could determine the winner of the group that also includes India and Pakistan.

Bangladesh captain Jahanara Alam was distraught after the defeat.

"We all are very upset at losing three games in a row and I am very worried about our bowling and fielding standards," she said. "I can't understand what is going wrong. We are making too many mistakes.

"Hopefully we will do better in our last game." Bangladesh play Pakistan in New Delhi on Thursday.

In Mohali, Sri Lanka scored 129 for seven after electing to bat and then restricted Ireland to 115 for eight with Sugandika Kumari claiming three wickets for 24 runs.

Sri Lanka was reduced to 59 for five by the 10th over when Eshani Lokusuriyage walked in to rescue her team with an unbeaten 35 off 28 balls.

Ireland's batters were tied down by steady Sri Lankan bowling, with only Cecilia Joyce (29), Isobel Joyce (24) and Laura Delany (29) getting among the runs.

"It was a good win," said Sri Lankan captain Chamari Atapattu, who scored a useful 34 at the top of the order.

"I played my natural game. We had targeted a total of around 140 but could not get that. However it all worked out in the end."

Sri Lanka suffered a blow when leading all-rounder Shashikala Siriwardene, who did not play the match due to a hamstring injury, was ruled out of the rest of the tournament.

Irish veteran Ciara Metcalfe, who took four wickets in Sri Lanka's innings, said she was delighted with her own performance but was disappointed by the loss.

"Look, I am obviously happy with the way I bowled, but the defeat has hurt us," she said. "We thought we should have won today. But we will take it in our stride and continue to improve."
