Clermont returned to the summit of the Top 14 standings in style on Saturday while Castres climbed out of the relegation zone thanks to a hard-fought win over Oyonnax.
Clermont moved above Toulon thanks to a bonus-point win over Lyon while Grenoble maintained their unbeaten home record as they battled past Bayonne.
Elsewhere, Bordeaux-BÃ¨gles came from behind in a grandstand finish to snatch a last-gasp win at La Rochelle – despite playing for eight minutes with 13 men – to rocket up into the top four.
Castres 27-18 Oyonnax
Stade Pierre Antoine, Castres
A precious win for Castres as they climb out of the drop zone, but it wasn't easy going against an ambitious Oyonnax side.
It wasn't pretty in a match between a home side desperate not to lose and a visiting team that was happy to disrupt the locals.
Castres led 13-6 at the interval thanks to a try from hooker Brice Mach off the back of a maul and a yellow card to Oyonnax lock Leon Power, who paid the price for pulling jumpers down in the line-out.
Castres started the second half badly as Jannie Bornman was sin-binned for a tackling Pedrie Wannenburg in the air but Rory Kockott scored a great try as he collected his own chip ahead to give his team a nine-point lead going into the final half-hour.
Oyonnax kept fighting however. Fly-half Regis Lespinas took his successful penalty count to five to keep the visitors in touch. Lespinas then landed a drop to cut the gap to just three and CO looked in danger when Ibrahim Diarra saw yellow for not rolling away.
Man-of-the-match Kockott slotted two late penalties however as Castres held on for the win that sees them climb to 11th in the standings.

Clermont 43-12 Lyon
Parc des Sports Marcel Michelin, Clermont Ferrand
Another masterclass from Clermont, who scored 27 unaswered points after break to cruise to a bonus-point win. New fly-half Camille Lopez was outstanding once again.
At try on the half-hour mark from Aurelien Rougerie and four Lopez penalties saw Clermont lead 16-12 at the interval.
Kiwi fly-half Stephen Brett kicked three penalties and a drop goal for Lyon in the first half to keep the visitors in the hunt but it was one-way traffic in the second period.
Clermont stretched their lead after the break via a wonderful try as Lopez found Rougerie on the switch before the centre offloaded to Benson Stanley, who finished in the corner.
Hooker John Ulugia added the third try on the hour mark after a great offload from lock Sebastien Vahaamahina. Fritz Lee scored number four from Uwa Tawalo's break and offload as Clermont turned up the heat against a LOU outfit that had no reply.

Grenoble 24-15 Bayonne
Stade des Alpes, Grenoble
After a strong start, Grenoble let Bayonne back into the game but managed a final push to secure the win. Bayonne will be disappointed to leave empty handed after playing some attractive rugby.
Grenoble led 13-6 at half time thanks to an early try from prop Richard Choirat and couple of penalties from fly-half Jonathan Wisniewski.
Grenoble number eight Rory Grice powered over from short range on the hour mark to put the hosts 18-12 up but Bayonne fly-half Blair Stewart kept the scoreboard ticking and his team in touch with a flawless kicking effort from the tee.
Indeed, the teams were separated by just three points with ten minutes to play but Wisniewski's fifth penalty ensured les IsÃ©rois remain unbeaten on home soil.
