Ireland 107 for 3 (Delany 44, Stirling 30*) beat Netherlands 106 (O'Dowd 51, Campher 4-26, Adair 3-9) by seven wickets
Abu Dhabi: Curtis Campher took a remarkable four wickets in four balls to lead Ireland to a seven-wicket victory over the Netherlands in the T20 World Cup.
Seamer Campher reduced the Netherlands from 51-2 to 51-6 in the 10th over before they were bowled out for 106 off their 20 overs in Abu Dhabi.
Campher is only the third man to claim four wickets in four balls in T20 internationals.
He then hit the winning runs as Ireland reached 107-3 with 29 balls to spare.
Ireland move top of Group A, with the first two teams in each group qualifying for the Super 12 stage.

The Netherlands made a poor start to their innings, with opener Ben Cooper run out for a duck off the third ball after a mix-up with Max O'Dowd.
Bas de Leede was then bowled by Josh Little, playing an ill-advised ramp shot, but the Dutch did recover to reach 50-2 off nine overs before Campher ripped through them in his second over.
O'Dowd went on to hit 51 off 47 balls, but another late collapse from 105-7 to 106 all out, with Mark Adair claiming 3-9, meant the Dutch could not post a challenging total.
Opener Paul Stirling made an unbeaten 30 off 39 balls and Gareth Delany hit 44 off 29 to ensure Ireland were well in control of the chase before Campher tapped a single to complete victory.
