France remain firmly on course for the Grand Slam after cruising to a 46-20 victory in their RBS 6 Nations clash with Italy in Paris.

Centre David Marty, preferred in the starting line-up to Mathieu Bastareaud, scored two tries in eight minutes while Italy were down to 14 men with Gonzalo Garcia in the sin bin.

Winger Marc Andreu and flanker Alexandre Lapandry both scored their first tries for their country, with others coming from Imanol Harinordoquy and Yannick Jauzion, and Morgan Parra kicked seven goals from nine attempts to give the French a 46-6 lead.

The outclassed Azzurri produced a spirited rally which brought them late tries through replacements Carlo Del Fava and Pablo Canavosio and Mirco Bergamasco added both conversions to two early penalties to give the score a touch of respectability.

It was Parra who created the game's first try, jinking his way through the Italian defence to get Harinordoquy over and he kicked the first of two penalties to make it 10-0.

The Italians' cause was made all the more difficult on 17 minutes when centre Garcia, fresh from a spell in blood bin, was sent to the sin bin for an obstruction of Andreu, who has been released on an exciting touchline dash by Poitrenaud.

France immediately made the extra man count as Marty coasted through a gap in the stretched Azzurri defence to score his side's second try, with Parra extending their lead to 17-0 with the conversion.

Poitrenaud demonstrated his attacking flair again on 27 minutes to help get Harinordoquy into space and he sent Marty over for his second try while the Italians were still down to 14 men.

Andreu came in off his wing to produce a scything run that took him all the way to the line, and then produced the break that got Jauzion romping over.

Parra was off target for the second time with a long-range penalty but he was back in the groove on 65 minutes to convert a try by Lapandry, who produced a strong finish to a break from fellow replacement Julien Malzieu before Italy rallied late on.
