Stade Toulousain youngster Nicolas Bézy failed to convert his own last-minute try, allowing giant-killers Montpellier to complete a memorable win double.

Bézy's miss left Fabien Galthié's side narrow 22-21 winners at the Stade Yves du Manoir as they followed up Saturday's shock 16-6 away victory at Perpignan, and in the process strengthened their own top six standing.

Their latest victory was just reward for another confident performance as they failed to panic after Vilimone Delasau's try helped the visitors into a 9-16 half-time lead against the run of play Twenty-one-year-old fly-half Bézy converted that effort, to go along with three earlier penalties as pre-match league leaders Toulouse proved clinical in attack.

But three penalties from Argentine Martin Bustos Moyana kept Montpellier afloat, and the utility back - playing at scrum-half tonight - was then the key figure as the hosts rallied after the break.

The 25-year-old kicked his fourth penalty success on 45 minutes and then broke through for a try two minutes later, which he also subsequently converted. His fifth penalty on 51 minutes then put Montpellier 22-16 ahead, setting up the dramatic finale when Bézy, cruelly, squandered the chance to snatch it for Toulouse with the last kick of the match.

  Leading try and point-scorers in Top 14

Elsewhere, Ollie Phillips and Sergio Parisse score two tries apiece as Stade Francais beat Castres 40-34 in an entertaining match at the Stade Charléty.

The Parisians crossed five times in a dominant opening half, with hooker Dimitri Szarzewski beginning the points-fest when he touched down after just five minutes for this third try of the season.

Parisse (handling skills and strength) and Phillips (pace and spatial awareness) then showcased their respective talents as they each ran in two tries before the break, at which point a home rout appeared on the cards with Stade already 37-17 ahead.

Only four penalties from Sérémaia Bai penalties and a Josefa Tekori try had kept Castres within 20 points, and it was difficult to envisage an unlikely comeback at that stage. But the visitors made numerous changes early in the second half and once Julien Dupuy's penalty had seen Stade past 40 points for their third successive home match it became something of a struggle for Michael Cheika's side.

Flanker Ibrahim Diarra and centre Yoan Audrin both scored in a three-minute purple patch around the hour mark for the visitors and they even had a last-minute chance to win the match when Yannick Caballero was only denied a try after television replays showed he had dropped the ball.

Stade even played most of the final quarter a man down after Argentine Juan Manuel Leguizamon was yellow carded in the 68th minute, just 10 minutes after coming on as a sub for Antoine Burban.

As it was, Stade Francais did just enough - if you can say that about a side that scored five tries - to secure their third home win out of three, and a points-advantage lead at the head of Top 14. 

England international Jonny Wilkinson kicked all 15 points as Toulon edged to a narrow 13-15 away win at La Rochelle.

The 31-year-old fly-half landed a hat-trick of drop-goals and two penalties as Philippe Saint-André's side made it two away wins from two to sit alongside their brace of home defeats after a strange opening to the season.

Wilko's boot kicked Toulon into a seemingly comfortable 0-12 half-time lead, but they betrayed a lack of confidence in the second half as they made too many errors which encouraged a valiant La Rochelle to rally.

Substitute Benjamin Dambielle slotted penalties in the 45th and 57th minutes before veteran winger Norman Ligairi touched down three minutes from time to prompt an anxious finale. Dambielle's conversion brought the 'Maritimers' to within two points, but that's how it stayed as the Top 14 newcomers had to settle for just a defensive point.

Dimitri Yachvili kicked three first-half penalties to put Biarritz 7-9 up away to Perpignan before the Catalans rallied through a second-half try from hooker Guilhem Guirado, eventually winning 17-12 to avoid a second successive home defeat.

Yachvili was on target in the fourth and seventh minutes as the Heineken Cup runners-up started brightly, but an opportunist try from scrum-half Kevin Boulogne brought the Catalans back into play just after the half hour. The former Albi player converted his own try to put Perpignan briefly 7-6 ahead, before Yachvili's third success of the half left the Basques 7-9 up at the interval.

The game's turning point proved to be Jérôme Thion's 48th-minute yellow card - as the result of a punch up - which then enabled Perpignan to turn the screw. Six minutes later they used their man advantage to good effect when Guirado was helped over the line by his fellow forwards. Boulogne was again on target with the conversion, before young fly-half Thomas Bosc extended their lead with a drop-goal from the 22.

There was still time for Yachvili to add his fourth penalty of the evening, with the kick enough to earn Biarritz a defensive bonus. That didn't, however, prevent their third successive league defeat as they slipped further down the table to 11th position.

On a night of close matches Bayonne recovered from 0-12 at home to Brive to win 19-18 after Mathieu Belie and Jamie Noon had both touched down for the visitors in the opening 10 minutes.

Julien Audy's 14th-minute response began the Bayonne fight-back, and the former Montauban scrum-half converted his own try before adding five penalties to seal the narrow win.

There were also two yellow cards, with Bayonne's Pierre-Philippe Lafond and Brive's Georgian hooker Vasil Kakovin both being sin-binned in the second half after Bayonne went 19-18 ahead.

The victory left Bayonne on 13 points with three wins from four after an excellent start to the 2010/11 season, whereas Brive, by contrast, have now lost three out of four and find themselves just one point off the drop zone. Sunday's home clash with Toulon will prove another tough assignment for Ugo Mola's men, who have already played Racing, Perpignan and Clermont in a testing start to the new season.

And it was party time for Bourgoin after they held off SU Agen to win 22-15 and register their first points of the season. They even managed their first try of the season as well, with number eight Tim Cowley going over in the 25th minute.

Their remaining 17 points came from the boot of former Leeds fly-half Alberto Di Bernardo - via five penalties and a conversion - but Agen's Conrad Barnard also managed five in return to ensure the visitors at least earned the defensive point.

That was enough to keep them just ahead of Bourgoin in their ongoing basement squabble, but the home side will just be relieved to have finally got their season underway. Next up Bayonne at home on Sunday.   

In the late game in-form Racing-Métro beat champions Clermont Auvergne 28-17, with fly-half Jonathan Wisniewski kicking 20 points.

The Parisian No 10 has now amassed 68 points in just four matches as he strives to hold on to his starting slot now that Juan Martin Hernandez is back up and running.

There was also a try apiece for the two sides with Racing's coming on the half hour from winger Julien Saubade, and Clermont's from new hooker Ti'i Paulo midway through the second half.

The win was revenge of sorts for Pierre Berbizier's side after their quarter-final defeat against Clermont last season, with the home side even having the double satisfaction of overcoming Benjamin Fall's early yellow card and denying their guests a defensive bonus.

The result leaves them one point behind the leading trio of Stade Francais, Bayonne and Montpellier, with a trip to Castres to come at the weekend.
