Wynnum Manly suffered a blow to their finals chances at the weekend after being stunned in a 38-26 loss to Norths and Bishop Park on Sunday.
In a congested ladder with a number of teams jostling to claim sixth, the Seagulls needed a win to stay in the running.
However, they got off to the worst possible start with Devils winger Michael Lucas scoring in the opening minute of the match.
While Dan Wallace hit back for the Gulls soon after, the rest of the half belonged to the home side who got out to an 18-6 halftime lead thanks to a double from speedy fullback Shaun Carney.
Wynnum Manly’s custodian Daniel Ogden responded in kind to resume the second half to cut the deficit, but that was undone when the Devils’ Kennedy Pettyborne was able to bump off defenders to score.
Lucas got his double soon after before dangerous Devils half Todd Murphy crossed in the 61st minute to cement a match-winning lead for this side.
However, the Seagulls attempted to mount a comeback with Wallace getting his second after intercepting the ball, while Pat Templeman scored twice in the final four minutes to bring further respectability to the scoreline.
For the Devils, half Murphy had the ball on a string all afternoon, and slotted all six of his conversion attempts – as well as a penalty goal for good measure.
