The West Indies got their third win in a row with a tense three-wicket win over Sri Lanka to open their Super Six campaign at the ICC Under-19 World Cup in South Africa on Tuesday.

Sri Lanka first posted 231 from their 50 overs after winning the toss and choosing to bat first at the Diamond Oval in Kimberley.

Dinura Kalupahana made 53 from 83 balls to lead the Sri Lankan batting effort while Malsha Tharupathi made 42 off 38 and Supun Waduge 31 off 40 to provide good support.

Raneico Smith took 4-47 from his 10 overs to lead the West Indian bowling effort while Nathan Edward took 2-47 from his nine overs. Nathan Sealy and Tarrique Edward took a wicket each.

The West Indies then completed a tense chase, reaching 232-7 from 49.3 overs.

Steven Wedderburn, playing only his second match of the tournament, led the way with a 71-ball 61 at the top of the order. His knock included five fours and three sixes.

He was well supported by Jordan Johnson who made 39 off 46 balls including four fours. Captain Stephan Pascal made a swift 26-ball 33 including five fours and a six.

The West Indies were cruising at 147-2 in the 27^th over before Wedderburn and Johnson fell in successive overs to leave the West indies 149-4 in the 28^th over.

The subsequent wickets of Mavendra Dindyal (17), Nathan Edward (13) and Jewel Andrew (11) left the West Indies in a tricky position at 206-7 in the 46^th over before a match-winning 26-run eighth wicket partnership between Nathan Sealy and Tarrique Edward.

Sealy finished 27* off 28 balls while Edward finished 11* off 13 balls.

Vishwa Lahiru took 2-32 from his 10 overs for Sri Lanka while Dinura Kalupahana and Sineth Jayawardena also took a pair of wickets, each.

The West Indies are now second in Group two of the Super Six with four points, the same as Australia who play England tomorrow. The Caribbean side will play Australia in their final Super Six game on Friday.

The top two teams in the group will advance to the semi-finals.
