Ospreys needed a Dan Biggar drop goal seven minutes from time to get past Scarlets in Llanelli in a game dominated for long periods by the home side. Stepen Jones had a late opportunity to snatch a draw but his penalty drifted wide. Ospreys begin their European campaign next Saturday with a trip to the Stade Felix Mayol and a meeting with Toulon.
Toulon prepared for that clash with a home 22-12 win over Castres, Jonny Wilkinson once again their main points contributor, scoring 17 of their total courtesy of a conversion, drop-goal and four penalties. Their try was awarded by English referee Andrew Small just before the break, Wilkinson's conversion giving them a 19-6 interval lead. 
London Irish were also at home ahead of Munster visit. Less than 7,000 turned up to the Madjeski to watch their side beat bottom of the ladder Leeds. Sailosi Tagicakibau who came on as a 55th minute replacement scored twice in Irishs' 40-24 bonus point win.
