The greater all-round fluency of The King's Hospital was their greatest companion as they beat Pres Bray at Donnybrook to reach the Vinnie Murray Senior Cup final.
The winners overcame the loss of captain Rolus Olusa and primary goal-kicker Sam Dowds within the first five minutes.
Replacement centre Daniel Courtney powered his way over for the first try and back-up kicker Paul McCullagh was good for seven points.
The result was tough on Pres inside-centre Cathal Martin, who scored all of his team's 14 points, his second converted try making it 15-14 in the 48th minute.
After that, KH No 8 Matthew Bursey showed up for a few crucial plays, taking a spilled ball for 60 metres to turn defence into attack and being the chief instigator for hooker Jack Perry's crucial 54th minute converted try.
