BBC Radio Wales Sport commentator Nick Webb deserves special praise - he commentated on the whole first half with a sock on his hand after losing his glove.

Ospreys asked most of the questions in that half with Alun Wyn Jones and Rhys Webb showing their international pedigree.
Liam Williams has handled most of what's been thrown at him on a wet and cold day, and the power of the Scarlets' scrum is giving them a finger-hold in the match.

Williams so solidpublished at 17:50 Greenwich Mean Time 27 December 2014
Liam Williams is a rock under the high kicks from Rhys Webb. And after his recovery to prevent Tyler Ardron scoring is an early man of the match contender. But there's a long time to go yet.

Rhys Webb is back on with a developing black eye.
