Wales scored two tries and punished France through the boot of Leigh Halfpenny to keep their title hopes alive with a 27-6 win at Millennium Stadium on Friday.
Unlike their performance against Ireland a fortnight ago, the Welsh pack came to the party, dominating the contact zones and shutting down all French attacks.
Wales led 20-6 at the interval thanks to an opportunistic try from George North, five penalties from Halfpenny, some interesting refereeing from Alain Rolland and a few howlers from Jean-Marc Doussain.
It was a dominant opening 40 minutes from the defending champions, who hardly allowed the French into their 22.
The second half saw just a single score, but skipper Sam Warburton's try sealed the win that reignites the Wales' hopes of claiming a third consecutive title.
