Young Munster advanced to a meeting with Cork Constitution in the final of the Bank of Ireland Munster Senior Cup after a 16-13 extra-time victory away to Cashel last Saturday.
The decider will be played at Irish Independent Park in what will be a repeat of last year's decider, which Cork Constitution won 14-7.
The Cookies needed a drop goal from Shane Airey in the first period of extra-time to decide the issue.
David O'Mahony opened the scoring with a penalty for Young Munster which Ollie McGlinchey levelled with one for Cashel.
A try by Kieran Murphy converted by McGlinchey put the home side in front and a second O'Mahony penalty left it 10-6 in Cashel's favour at half-time.
Colm Skeehan's converted try made it 13-10 to Young Munster and a second McGlinchey penalty sent the game into extra-time.
Knowing that Cashel were ahead on the first try rule, the visitors raised their game and Airey's drop goal saw them advance.
Con also claimed their 43rd Cork Charity Cup title last Friday night with an extra-time 17-11 win over Highfield at Woodleigh Park.
It took a 79th minute penalty from Con's Tomás Quinlan to send the game into extra time after Highfield had hit the front for the first time three minutes earlier with a Luke Kingston penalty.
Highfield dominated the opening period of extra-time but were unable to add to their tally as penalties on 94 and 97 minutes by Quinlan sealed victory for Con.
Quinlan and Kingston traded penalties in the first quarter before a yellow card for Highfield scrum-half Chris Bannon saw Con take control and Luke Cahill finished off a forward drive to score in the corner for an 8-3 half-time lead. Fintan O'Sullivan touching down to tie up the scores.
Four minutes later Kingston kicked his side into the lead and it looked like a 42-year gap since their last success was to end but Quinlan pounced at the death to send the game into extra-time with Con eventually coming out on top.
