Ireland took full advantage of ideal batting conditions and a tired Sri Lankan bowling attack to pile up 492 all out before the hosts responded by reaching 81-0 at stumps on day two of the second Test on Tuesday (April 25).
Nishan Madushka was unbeaten on 41 in only his third test match, and Sri Lanka skipper Dimuth Kurunaratne remained not out on 39 when play was suspended 30 minutes before the scheduled close due to bad light and rain.
Earlier, Ireland reached its highest Test score by a distance, surpassing their previous best of 339 against Pakistan in 1998 in Dublin.
