Second met third in the Principality Premiership at the weekend as Swansea were comfortably beaten by Aberavon.

League leaders Pontypridd were held to a 16-16 draw by struggling Cardiff in a messy game at Sardis Road.
Winger Jimmy Norris raced through to score for Cardiff while centre Adam Thomas stormed over the line for the hosts.
“That was a massive improvement,” said Cardiff backs coach Lee Jarvis who starred for both Cardiff and Ponty as a player.
“We worked on a few things in the week as far as our attack and defence goes and it’s good to see those things come through. But rugby is a simple game and we turned up with an attitude that I haven’t seen all season and it showed in the way we played.
“It was nip and tuck right the way until the end. We had our chances in the second half and we let them off the hook a couple of times as well.”
Llanelli dominated their mid-table match with Bedwas, winning 28-3 and taking a bonus point in the process.
