Brecon Corries claimed the derby bragging rights on Saturday afternoon, after scoring four unanswered second-half goals within the space of 12 minutes, to record a 5-0 win over rivals Hay St Marys at the Rich Field.
The hosts broke the deadlock in the ninth minute, when the experienced Paul Keddle drove towards the penalty area and his low shot found the bottom corner of the net.
The Saints, who saw manager Gareth Jenkins stand down following the home defeat to Undy Athletic, came close to levelling the scores in the 24th minute but Ollie Woods was unable to reach a Matty Tong cross delivered to the far post.
Brecon Corries had to wait until the hour mark to double their advantage when Joel Evans headed a lofted ball, played into the penalty area by Craig Evans, over the head of Tom Lewis in the Saints’ goal.
Three further goals in the next 12 minutes secured all three points for the Corries.
Joel Evans squared the ball across the goalmouth in the 67th minute for substitute Andrew Hamnett to convert at the far post.
The Saints lost the ball two minutes later when attempting to play out from the back, but Joe Cooper was put through on goal to slide the ball past Lewis.
Cooper doubled his tally three minutes later when he drove into the penalty area from out on the left wing before coolly finishing past the Hay St Marys goalkeeper.
Woods had an opportunity to net a consolation in the 83rd minute but directed his shot wide of the far post following good approach play by Jack Biggs and Brendan Hackett
Brecon Corries were left to celebrate a victory that cemented their position in the top-half of the table as the Saints were left to reflect on another chastening result.
