Ospreys made it back-to-back RaboDirect PRO12 victories with a 32-3 victory over Welsh rivals Scarlets in a heated clash at the Liberty Stadium that saw two red cards.

After the Ospreys won at Parc y Scarlets in September they were again the dominant side with a penalty try and two further tries for lock James King and skipper Kahn Fotuali'i. Fly-half Dan Biggar added 14 points with the boot and Fotuali'i also kicked a drop-goal as Ospreys stormed to victory in front of a crowd of 19,443 in Swansea.

The Scarlets were not helped that they had replacements Rob McCusker and Gareth Owen sent off in the final minutes and also had another three players sin-binned - George Earle, Tavis Knoyle and Aled Thomas.

Elsewhere, Cardiff Blues returned to winning ways in this season's RaboDirect PRO12 with a narrow 12-10 victory over Dragons at the Arms Park.

The Blues moved above Edinburgh and Treviso into seventh place in the table after getting the better of the mud bath to claim just their third win in their last 14 matches in all competitions. They were under the cosh for much of the match, but pulled through thanks to four penalties from teenage fly-half Rhys Patchell. The Dragons claimed the only try of the contest through centre Andy Tuilagi but were left to rue other missed chances during a game played in appalling conditions.

Blues boss Phil Davies heaped praise on Wales skipper Sam Warburton after a pivotal performance. "Sam was excellent. He was really good," said Davies. "He's done well for me so far whenever he's played. I've got nothing but admiration for the guy.

"He's a fantastic player and this was one of his best performances so far. Defensively he was magnificent, not just with his tackling, but his decision-making of when to jackal and when to organise people in and around him. He had an excellent game."
