Hay St Marys concluded their Floodlighting and Electrical Ardal South East campaign on Saturday afternoon with a 3-1 defeat to Risca United at Forest Road.
The visitors broke the deadlock within five seconds of kick-off when the ball was rolled back to captain Jak Lewis and he proceeded to beat Saints keeper Rob Snedden from inside his own half of the pitch.
Risca United nearly doubled the lead two minutes later when Alfie Hutton somehow put his close-range effort wide of the far post following an inviting low cross by Connor Evans from out on the right flank.
The rampant Cuckoos had another good effort in the fifth minute but Lloyd Oliver was unable to keep his snapshot on target after latching on to a header by Hay St Mary's defender Matty Meredith that fell short of Rob Snedden, deputising in the Saints' goal.
Arthur Furness was unable to keep his 25 yard under the crossbar in the 15th minute prior to Oliver seeing his close-range finish ruled out by an offside flag six minutes later.
After having to withstand waves of attacks from their opponents, the Breconshire club had their first real opportunity in the 22nd minute when Jack Cripps was played through on goal, but the Saints winger could only find the side netting.
The Cuckoos were in no mood to sit on their one-goal advantage, with Furness heading over the target from a free-kick delivered from out on the right flank, before Oliver drove towards the penalty area three minutes later but could only direct his ensuing effort straight at Snedden.
Jack Biggs tried his luck from just over 30 yards out, following a poor clearance by Harry Morris in the visitor's goal, but his long-range effort drifted narrowly wide of the target.
Hay St Mary's manager Tom Weaver would have been pleased to go into the half-time break having only conceded one goal but knew his charges would have to provide more of an attacking threat if they were to claim their first league win of the campaign at the final attempt.
But Risca United doubled their advantage in the 72nd minute when Logan Oldridge fired in a low shot.
Immediately from the restart, Biggs was played through on goal by Noah Cripps but was unable to keep his effort under the crossbar, before the Breconshire club halved the deficit 10 minutes later when Noah Cripps turned the ball home from close range after Liam Macanally had seen a shot on target blocked.
Risca United were looking to re-establish their two-goal advantage and conclude the season on a winning note. Oliver was unable to keep his 85th minute effort on target following a cross from out on the right flank.
However, the Cuckoos confirmed victory in the second minute of stoppage time when Leon Thomas cut back inside and beat Snedden with his low shot from within the penalty area.
For the Saints it brought down the curtain on a difficult campaign as they look to rebuild next season back in the MMP Central Wales League.
