Wasps 19 Leinster 12: A losing bonus point keeps Leinster at the top of Heineken Cup Pool Two despite this defeat to Wasps at Twickenham. Michael Cheika's side now go into next weekend's clash with Edinburgh secure in the knowledge that a four-try win will guarantee their passage into the next round.

Josh Lewsey produced a vintage performance that inspired Wasps but their Heineken Cup ambitions remain up in the air. Wasps could live to regret allowing Leinster to earn a losing bonus point by accepting a late shot at goal instead of pushing for a try which would have seen them take control of the group.

As it stands now, Wasps must earn a better result in Castres next weekend than Leinster manage at home to Edinburgh in order to guarantee a place in the quarter-finals.

Wasps will be frustrated by the end result about as much as they were frustrated to see uncontested scrums introduced after Leinster lost two props inside 37 minutes.

By that point, Wasps had moved 16-6 ahead and scored the only try, finished by Serge Betsen but created by a lightning break from Lewsey and powerful run from his former England colleague Paul Sackey.

Lewsey retired from England duty after being overlooked during the November internationals but still has Lions ambitions and did his chances of selection no harm with an all-action display.

But Wasps will be left kicking themselves after four penalties from Felipe Contempomi ensure Leinster remain favourites to qualify as Pool Two winners.
