India [ Images ] defeated Sri Lanka [ Images ] to qualify for the semi-finals of the ICC [ Images ] Women's World Twenty20 [ Images ] on the last day of fixtures at Warner Park, while New Zealand [ Images ] rounded off its group stage with a comfortable victory over Pakistan earlier in the day.
India's match was the second of the day and the higher scoring of the two at Warner Park, with Sulakshana Naik and Mithali Raj [ Images ] both scoring half-centuries in a total of 145.
"It's obviously good to know we've now qualified for the semi-finals of the tournament and we're looking forward to facing Australia [ Images ] next in St Lucia," said India captain Jhulan Goswami [ Images ].
"I was very pleased with how we performed today; I felt Sulakshana Naik and Mithali Raj along with Poonam Raut all had Sri Lanka on the back foot from the start. We need to carry this good form to St Lucia," she said.
Naik smashed five boundaries on her way to making 59 runs and was mainly assisted in her innings by Raj after Poonam Raut departed for 12, bowled by Udeshika Prabodhani.
Upon arriving in the middle, Sri Lanka never quite matched up to India's batting and put up a mere 73 in reply, losing nine wickets, in its allotted 20 overs.
Diana David was by far the pick of the Indian bowlers, claiming an impressive 4-12 in a haul that included top-order batters Suwini de Alwis, Chamari Polgampola and Sripali Weerakkody.
Earlier in the day, New Zealand pace bowler Nicola Browne led her side's rout of Pakistan in the teams' final game of Group B to secure the team top place in the pool.
Browne, who took 4-15, demolished the Pakistan batting line-up. Sana Mir's side finished with just 65 for 9.
Having won the toss and electing to bat, only three of the Pakistan side made it into double figures -- Nain Abidi (11), Urooj Mumtaz (14) and Sania Khan (15).
New Zealand's bowling department, including the pace of Browne, was simply too strong for the team from the sub-continent.
"We didn't perform at all well in this tournament," said Mir.
"The only time we did well as a side was during the warm-up fixtures and this was not good enough for a world tournament. We need to go and improve our game as the standard of women's cricket has improved a lot in the last year and all credit must go to New Zealand who played extremely well today," she said.
New Zealand took just 8.2 overs to reach the target but not before they'd lost four wickets including that of opener Suzie Bates, who was caught by Mir, and Rachel Priest, who departed for just two runs.
It was up to Sara McGlashan and Liz Perry to see the White Ferns through and seal victory.
"It's obviously good to know we've finished top of the group but to be facing West Indies [ Images ] is going to be a challenge in the semi-finals in St Lucia. They are the kind of team that are so unpredictable at Twenty20, one day they could make 80 all out and another 180 for four so I'm not taking the upcoming fixture lightly.
"Hopefully they've watched today's game and seen what kind of a bowling attack we've got in our side," said New Zealand captain Aimee Watkins.
