Irish skipper Brian O'Driscoll scored twice and then hobbled off injured as Leinster inflicted a sixth defeat in eight games for struggling English club Wasps in Heineken Cup action over the weekend.

Leinster ran in six tries all told to claim a valuable bonus point victory and grab a stranglehold on Pool Two of the European competition.

O'Driscoll had both of his tries in the first half, guiding the Irishmen to a 15-11 lead, before limping off at the break with a knee injury.

London Wasps now face a must-win visit to Edinburgh where they will look to get their campaign back on track.

Wallabies flanker Rocky Elsom was among four Leinster players to cross for tries in the second half, the others coming from Luke Fitzgerald, Felipe Contepomi, who kicked 11 points, and Rob Kearney.

In other matches French giants Stade Francais ran in four tries as they overpowered Welsh club Scarlets 37-15, Edinburgh grabbed their first win on French soil when they toppled Castres 13-6 and Dan Carter's Perpignan lost an all-penalty affair 15-9 at Ospreys.

Byron Kelleher's Toulouse got up 22-16 over Glasgow in Scotland, while Harlequins moved to the top of Pool Four with a bonus point win over Ulster at home.

Reigning champions Munster displayed their European Cup pedigree with an impressive 24-16 second round Pool 1 victory over a strong Sale side.

In other games, Bath beat Newport-Gwent Dragons 13-9 in Pool 5, Cardiff Blues beat Gloucester 37-24 in Pool 6, while Montauban went down 24-19 to Clermont in an all-French Pool 1 clash.

Munster, bursting with Ireland internationals, were effectively marshalled by veteran outside-half Ronan O'Gara and outplayed the home side around the fringes.
