Cardiff mistakes cost them against a Llandovery side fighting for their Premiership lives.
The first quarter looked promising for the home side as they tried to move the ball through the hands, but when the killer pass was needed the ball was spilled. The Blue & Blacks took the lead through a Scott Snedddon penalty, but despite creating most of the chances it was the Drovers who scored first when Mike Saulo scored after a mix up in the home defence.
Suddenly it came right for the Blue & Blacks. Thomas Young was involved in most of the good things Cardiff were doing, and when he and Wales under 18s centre Thomas Pascoe combined to break into the visitors twenty-two Ellis Jenkins was on hand to score. Sneddon converted.
The second try can a few moments later and it was again Jenkins who scored after a sweeping move that saw forwards and back combine to create an overlap out wide. Sneddon added another penalty and the Blue & Blacks went in at the break 18-7 up.
The second half belonged to the visitors. First Shaun Jones nudged them closer with a short range try before another Cardiff knock-on led to a try for Lee Rees. Howard Thomas converted from wide out. Cardiff came back again when Richard Smith scored his tenth try of the season. It looked from there as if it would be the home side would be able to kick on from there and gain the win and the bonus point but it was the Drovers that kicked on to gain the bonus point try that gave them the win too.
Again it came from a Cardiff mistake and when the ball came out of the ruck Cardiff ran out of defenders and Matthew Jacobs was over in the corner. From wide out Thomas converted to give the Drovers points.
