Ireland beat defending champions Afghanistan by 122 runs to win the ICC Intercontinental Cup final in Dubai.
Afghanistan had been set 347 for victory but, resuming on 136 for five, it was always a daunting task for the holders and they were dismissed for 224.
Medium pace John Mooney was the star of the show for Ireland as he bagged 5-36 - his second five-wicket haul of the match - to finish with match figures of 10-81.
The victory continued Ireland's great run of success after they won the World Cricket League Championship title in the 50-over format in October and the ICC World Twenty20 Qualifier tournament in November.
This was their fourth success in the six runnings of this tournament.
"It is a fantastic feeling," said Ireland skipper William Porterfield.
"We had obviously set out to do that. We won the 50-over stuff with a couple of games to go. I think we only lost one game throughout that campaign which was great for ourselves. Coming here (in UAE) last month and beating Afghanistan in the ICC World Twenty20 Qualifier final was great.
"I think it is all because of the hard work we put in. We are a pretty hard working bunch any time we come away on tour. Over the last four or five years, we have become a lot more professional outfit both on and off the pitch. I think that has helped us massively with our cricket."
The Afghans had reached 189-5 at lunch and moved onto 199-5 after the break but the new ball did for them as they lost their last five wickets for just 25 runs in less than 14 overs.
Rahmat Shah finished unbeaten on 86.
