Treviso 5 (5)
Wasps 71 (33)
Tries: Sackey 3, King, Dallaglio, Reddan, Lewsey, Van Gisbergen, Haskell 2, Cipriani.
Cons: Van Gisbergen 8
England wing Paul Sackey ran in a hat-trick of tries as Wasps romped to an easy Heineken Cup victory away to Treviso in Italy.
In total Wasps, who led 33-5 at the break, ran in 11 tries, earning a bonus point and going top of Pool One.
Alex King, Lawrence Dallaglio, Eion Reddan, Josh Lewsey, Mark van Gisbergen, James Haskell (two) and Daniel Cipriani all scored tries.
Van Gisbergen was also on target with eight conversions for Wasps.
Victory lifted the 2004 champions two points clear of Perpignan, who they host in the next, penultimate round of matches in January.
Wasps' final group fixture is away to Castres.
606 DEBATE: How far will Wasps go in this season's competition?
Wasps director of rugby Ian McGeechan:
"I think we've gone up a level as we increased our tempo and we played in a very pleasing way.
"We've got a lot to play for over the next couple of weeks.
"We've got a huge Christmas period coming up and we've got to manage it properly, but I feel we are competing well in both the Premiership and in Europe."
Treviso second-row Michele Sutto:
"Wasps are more used to playing a more intensive rugby over longer periods, so it was hard for us to stay at the top of our game for the whole game.
"We managed that for the first 15 minutes and we were very motivated. But we wasted two or three chances and we paid for that."
