Mumbai: Sri Lanka skipper Kumar Sangakkara won the toss and decided to bat against New Zealand in a fierce tussle for final group positions in their last match ahead of the World Cup knockout round.
The pressure to qualify is now off with New Zealand and Sri Lanka joined in the last eight by fellow Group A sides Australia and Pakistan, but final positions are crucial as they determine opponents in the next round.
New Zealand have emerged as the tournament's dark horses, winning their past three matches, including an emphatic 110-run victory against the talent-packed but unpredictable Pakistan, their fourth success out of five.
The Black Caps have stumbled only once, against four-time champions Australia, but Daniel Vettori's men appear to have put that blip behind them.
New Zealand's only major worry in the run-up to the day-night match at the Wankhede Stadium in Mumbai is the fitness of Vettori and fast bowler Kyle Mills.
Vettori (knee) missed the 97-run win against Canada on Sunday while Mills left the field after only 2.4 overs of his spell with a strain in his left leg.
Runners-up in the 2007 edition, Sri Lanka have cantered to easy wins over Canada, Kenya and Zimbabwe but lost to Pakistan and saw their much-anticipated clash against Australia abandoned due to rain.
Sri Lanka have brushed aside the issue of having to play their final league game in Mumbai despite being one of the tournament co-hosts.
Only South Africa have confirmed qualification from Group B but finishing higher in the group could secure New Zealand or Sri Lanka a match against England, Bangladesh or the West Indies as opposed to the more highly fancied India or South Africa.
