But the win also went a long way to proving the Swansea club had shaken off the disappointment of missing out on promotion to the Premiership last season in a play-off and the loss of several key players and two coaches during the summer.
Skipper Darren Poland said: "Things were very disjointed at the club during the summer because of the Premiership clubs picking off some key players and it showed in a very poorly start to the season.
"But there was a lot of honest talking after the losing our first two games and since then everyone has responded really well. Everyone is working hard and things are starting to come back together again.
"We've set ourselves the target of finishing 2006 unbeaten which is a big ask but we've won five in a row now and confidence is growing."

Bargoed produced the performance of the day in the East with a workmanlike 23-16 win over fellow title contenders Beddau. Wing Lee Pearson raced onto a clearance kick by Jamie Howells to score the crucial try, Howells added five penalties and a drop goal gain revenge for the Mid Districts Cup Final defeat last season.
Coach David Lynch said: "On our way up the tables we enjoyed throwing the ball around but we had to prove our growing maturity against a big side like Beddau. We learned from our defeat in the final and executed a game plan to beat them. It showed how far this young team has come and we proved we can compete for the title."
