A strong second half showing made the difference between the two sides.
Abbeyleix St. Lazarians have finished second in Group B in the Laois Senior Hurling Championship.
Despite being down by one point at half time to Castletown, a powerful second half saw PJ Peacock's side secure a resounding 2-20 to 2-10 win on Sunday.
Two second half goals from Ciaran Byrne and Aaron Brennan, who made a big difference with 1-06, was enough for The Fung to see the game out.
The win now means they will face Rosenallis in the quarter-finals.
Their manager, PJ Peacock says they've competed in almost all their games this year so far:
