A second half debacle gifted the three points to Penrhyncoch when at half time a win looked on the cards.
The Bluebirds started the game like a house on fire not giving the visitors a chance to settle and were two goals to the good after 10 minutes following quality set pieces.
Luke Sherbon scored the first quickly followed by Steve Blenkinsop.Further chances were missed and Penrhyncoch were relieved to hear the half time whistle.
The second half was a completely different affair.The first Penrhyncoch goal came from centre bac Sion James who netted from 40 yards with keeper Luke Evans misjudging the flight of the ball.A quick fire brace from Jonathan Evans put Penrhyncoch in the ascendancy and with Caersws having little heart for the fight further goals came from Nashawn Blake and Rhun Garner.
The second half showing was one of the worst displays seen at the Recreation Ground for many years and unless there is a massive improvement it is going to be a long hard struggle to keep in this league
