Cardiff and Pontypridd served up a festive Derby full of passion at the BT Sport Cardiff Arms Park in front of a bumper holiday crowd.
Cardiff had the early pressure and after a series of penalties in the visitors twenty two that yealded no further sanctions James Whittingham put the Blue and Blacks ahead. it was a lead that lasted until half time bit the Catrdiff pressure should have been rewarded with more points. Only stern defence from Ponty kept them out. first Tom Slater burst up the middle but the move came to an end with a penalty to the visitors.
Just before half time a Ponty attack nearly handed Cardiff a try. As the ball was spread wide in the Cardiff 22 Dan Fish stepped in to intercept the pass. Only a tap tackle prevented him from going all the way to the other end.
The second half saw Ponty attack with more pace and the Blue & Black defence was eventually breached as the ball was moved along the line to give enough space for Lewis Williams to go over in the corner. Simon Humberstone landed the conversion but within a few minutes the home side narrowed the gap as Whittinham doubled their score.
But Ponty were to seize control as Williams again went over, this time in the other corner. Humberstone again on target to deny the home side what would have been at least a deserved bonus point.
