John Mooney's second five-wicket haul in the match helped Ireland post a 122-run victory over Afghanistan to win the ICC Intercontinental Cup final on Friday.
Defending champions Afghanistan, chasing 347 runs for victory, resumed at 5-136 but were dismissed for 224 on the fourth day of the five-day match.
Medium pacer Mooney took 5-36 in the Afghan second innings, giving him match figures of 10-81.
This was Ireland's fourth title in six editions of the Intercontinental Cup.
But it was the first time a team had won three ICC tournaments across three different formats in the same calendar year.
Ireland won the World Cricket League Championship title in the 50-over format in October and the ICC World Twenty20 Qualifier tournament in November, to go with the Intercontinental Cup title in the longer format.
"It is a fantastic feeling," said Ireland skipper William Porterfield.
"We had obviously set out to do that.
"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."
Rahmat Shah and captain Mohammad Nabi took Afghanistan to 5-189 at lunch.
However, things changed after lunch when Ireland decided to take the second new ball in the 82nd over at 5-199.
Mooney ran through Afghanistan's lower order as the defending champions lost their last five wickets for 25 runs in just under 14 overs with Rahmat Shah stranded on 86.
