Ireland skipper William Porterfield lamented the loss of "avoidable" wickets in his side's 79-run defeat to Sri Lanka in the one-day international at Clontarf.

“We bowled very well and I thought we were unlucky not to restrict them to less than 220," the Tyrone man told RTÉ Sport.

“They played a couple of good shots. Mendis [18 not out] came in and got a few away but that can happen in the last couple of overs.

“Matthews [30] could have been run out and had a couple of top edges that went between fielders.

"On another day they go to hand and you’ve got them even more on the back foot but that’s cricket.

Porterfield admitted that a mid-innings collapse of four wickets for just 11 runs, following a steady start, was decisive.

“We did all right to get through the first 15 [overs] and up to around 60 for two, especially the way they bowled in the first eight to ten overs.

“But the next six to eight overs is where we lost the game.  We lost some quick wickets and a couple of them were avoidable.”

Ireland will have a chance to avenge the defeat when they face Sri Lanka in Clontarf again on Thursday, in the second ODI.
