So an easy win for Sri Lanka while Ireland will be very frustrated with their batting display which collapsed under pressure from the tourists' attack.
Ajantha Mendis has been named man of the match his spell caused Ireland all sorts of problems and he picked up three wickets.
The second ODI will take place on Thursday and we will be here again to see if Sri Lanka can complete the series whitewash. But from Conor Hayes in a cool and overcast Clontarf, it's goodbye.
