After four consecutive wins the Blue & Blacks hit the rocks at an Arctic Arms Park with a poor performance against basement outfit, Ebbw Vale.
The writing was on the wall in the first minute as sloppy handling deep inside the visitors’ half saw Cardiff boomeranging back to their own line.
To compound the error Leon Andrews then made a hash of an attempted clearance kick and number 8 Manu Tuipolotu was driven over for the softest of tries.
Byron Hayward, a specialist thorn in the side of more than one Cardiff side over the years, added the points and then kicked a 30-metre penalty goal.In the 25th minute Mike Scudamore scored a second try for Vale, inevitably converted by Hayward from far out, before the Blue & Blacks were shaken out of their slumbers.
Liam Roberts opened their account with a fine try after good work by Richard Jones, on as a replacement for Dean Dewdney, and then scored an even better one as he swerved, sidestepped and sprinted 60 metres for a touchdown at the posts.
Chris John converted both and as he had also kicked a penalty goal the Blue & Blacks had remarkably cancelled out a 17-point deficit in the space of four-and-a-half minutes.
Any hopes on capitalising on the unlikely half-time equality soon evaporated. Hayward was influential again as Lenny Woodard touched down in the corner and the conversion flew over from the edge of the right touchline.
Another Chris John penalty goal was not enough to stem the Vale’s attack and in the 62nd minute they were awarded a penalty try, converted by Hayward.
In injury time Elgan Jones squeezed over in the corner but it was too little, too late.
