IRELAND captain William Porterfield lashed his players for making 'schoolboy' errors after two resounding reality checks in the space of 24 hours at the World Twenty20.

Having bowled poorly to let New Zealand get off to a flyer in yesterday's Super Eights opener, Ireland capitulated to 115 all out, 83 runs short, after four batsmen were run out.

While recognising New Zealand's supreme athleticism and dead-eye accuracy in the field, Porterfield admitted that John Mooney's dozy demise at the hands of Brendon McCullum – coupled with Regan West's failure to ground his bat against India the night before – painted his side in an unflattering light.

'You are always going to get run outs when you are under pressure but a couple of run-outs in the last two games have been pretty schoolboy really,' Porterfield acknowledged.

'We've got to improve on that because there is no place for them at this level.'

Porterfield also admitted that Peter Connell's replacement of Boyd Rankin was a gamble that didn't pay off as Aaron Redmond plundered 14 runs from Kiwi-born Connell's only over.

'We didn't bowl to the fields we had set and we let them get away from us at the start. There was only room for one of Boyd and PC and it was a toss-up between the two but things had just got away from in the last couple of games.

'We went with PC today and obviously things didn't work out,' said Porterfield, whose side now have a day off as they travel to London for games on Sunday and Monday against Sri Lanka and Pakistan.

'We know what's required at this level and today we just didn't execute our skills. It was a game we thought we could win. But we will keep going and bounce back.'
