Ireland captain William Porterfield blamed Gary Wilson's controversial reviewed dismissal for his side's 44-run defeat to West Indies in Mohali.
Wilson was adjudged lbw by umpire Asoka de Silva after his breezy 61 had threatened to drive Ireland to a much-needed victory in pursuit of West Indies' 275. Wilson reviewed the decision and despite TV replays suggesting he was hit outside the line of off stump, De Silva refused to change his decision claiming that the right-hander had failed to play a shot.
After watching the replay on the big screen, Wilson argued the point with the umpires - an action that could earn him sanction from the ICC - before he was eventually forced to leave the field. And Porterfield said: "The decision was crucial and cost us the game. When you have the technology and advantage of TV replays, that is supposed to eradicate mistakes."
He added: "I think it (the Decision Review System) is a good thing. The umpires are human, players make mistakes and umpires make mistakes - that's acceptable in the game.
"But in terms of the technology, once you've gone up to the technology then surely there can't be any mistakes from there. Something as clear as that, you've got everything in front of you
"The on-field umpires have watched the replay on the big screen, the third umpire has watched the replay and then it has come back to the on-field umpire and he's determined he wasn't playing a shot. How you can get that from that video footage I'm not sure - you'd have to ask him."
Ireland were within chasing distance of the target when Wilson was dismissed needing 77 from 51 balls with five wickets in hand.
The Associate nation also had the batting powerplay up their sleeve, but Porterfield said they were forced to delay using it as Wilson's dismissal came amid a debilitating run of five for 24.
"We lost a couple of wickets at that stage, that being one of them, that set the powerplay back for us," he told the BBC. "If Wilson is there along with Kevin (O'Brien) for that powerplay needing the seven-and-a-half or maybe eight an over at that stage then we are in with a great shout.
"We lost a couple of wickets quickly and the way we lost that one set us back a bit."
