A faultless kicking display by former England great Jonny Wilkinson provided the backbone to Toulon\'s sixth win in six Top 14 matches on Saturday as they ran out 33-12 winners over highflying Castres. Wilkinson\'s 18 points plus three tries - which gave Toulon a bonus point to boot - took them seven points clear of champions Toulouse, who thrashed Bayonne on Friday although that gap could be closed depending on results later on Saturday. Toulon wasted little time in taking the match by the scruff of the neck as Wilkinson first punished a Castres infringement with a penalty and then converted former Wallaby star Matt Giteau\'s try, after the latter had intercepted a Castres pass and touched down. The visitors got themselves off the mark shortly before the 20 minute mark through a superb long range penalty by South African scrum-half Rory Kockott after France centre Maxime Mermoz went offside. They reduced the gap further soon after when Toulon\'s English fullback Delon Armitage was penalised for a high tackle and Kockott made no mistake while the referee gave the Toulon a players a talking too about their high penalty count. However, the hosts answered in the best fashion possible as scrum-half Frederic Michalak slipped a pass to hooker Jean-Charles Orioli 22 metres out and he broke three tackles to touch down - Wilkinson added the conversion for 17-6. Castres, though, wouldn\'t give up and two more penalties by Kockott kept them in touch, though, the South African ruined his perfect record as a penalty - again the fault of Armitage - hit the post. Wilkinson made it 20-12 early in the second-half as he dropped a goal in front of the posts after being set up by Michalak and stretched the lead further in the 53rd minute with a penalty. Five minutes later the Englishman added another penalty to leave Castres requiring two converted tries to get their noses in front. However, it was Toulon who got a try as Wilkinson fed Mermoz who passed to former Wallaby George Smith and he broke through the Castres centres to touch down under the posts - Wilkinson converted to send the home supporters into rapturous celebrations. Later on Saturday 2010 champions Clermont host Grenoble while Biarritz seek to bounce back, after losing their unbeaten record last weekend, away at Racing-Metro and the latter\'s Parisian rivals Stade Francais bid to gain a crucial win after a desperate start at home to 2009 champions Perpignan.
