London Wasps wing Paul Sackey scored a crucial try for his side in a 19-13 win over Castres Olympique at Adams Park

The sides scored one try a piece, with the boot of Jermey Staunton making the final score in favour of the 2004 Heineken Cup winners  

 Staunton kicked penalties after six, 17 and 33 minutes to edge his side in front, with Ross replying twice, and Wasps’ best efforts were counter-attacks from long range until they established a toehold in the Castres 22.

The try finally came with the last move of the half after a dozen phases when Sackey accelerated in from his wing onto a short pass from Eoin Reddan and through a gaping hole in the defence around a ruck 10 metres out, and Staunton followed up by converting from in front of the posts.

Castres responded by kicking for the corners and set up a scoring position when Wasps were forced to concede a five-metre scrum five minutes into the second half.

The first drive for the line was repelled but Georgian prop Giorgadze forced his way through Lawrence Dallaglio’s tackle to score, with Ross converting from wide on the right.

Lewsey was forced off after aggravating a hamstring injury and his struggling side made a tactical switch when Alex King replaced Staunton at fly-half after 55 minutes.

But the home side survived more near-misses on the hour when first Pablo Canavosio went close and then Ross’s cross-kick just eluded diving wing Laloaoa Milford.

Wasps finally broke out in the 70th minute when Tom Voyce chased a long clearance to force a five-metre scrum.

Castres flooded offside after Dallaglio picked up and van Gisbergen kicked the resulting penalty, that proved to be the final score of the match.
