Parisse was instrumental in at least three of Italy’s six first-half tries, scoring the first and setting up two others as the clinical Italians dominated the forward exchanges to notch 50 points for the first time in a World Cup match.

“We are very happy to take the victory and the five points which was very important for us to try and qualify (for the quarterfinals),” Parisse said in a pitch-side interview.

“We scored some tries and we take confidence in our attack but our defense we must improve because the USA and Ireland will be very hard,” he added of their final two pool opponents.

Winger Giulio Toniolatti and center Tommaso Benvenuti also scored two tries each, while scrumhalf Edoardo Gori, winger Luke McLean and Alessandro Zanni also crossed for the Italians.

The Italian scrum, which constantly had the Russians on the back foot, was also rewarded when referee Waynes Barnes gave a penalty try after the Russians had collaped the scrum for the fourth time on their goal line.

Flyhalf Riccardo Bocchino converted four of their first half tries, though he and Benvenuti missed five conversions between them.

Italy hooker Fabio Ongaro was sin-binned for an illegal tackle on Igor Klyuchnikov when he went into the tackle without wrapping his arms around the Russian fullback.

Russia took full advantage when replacement scrumhalf Alexander Yanyushkin darted over for his side’s first try at the World Cup and flyhalf Konstantin Rachkov converted from wide.

Benvenuti gabbed his second try of the game when he kicked ahead and won the race to the ball to give the Italians a 43-7 lead shortly after the halftime break, before Russian Vladimir Ostroushko scored his side’s second try after a sustained buildup.

Italy winger McLean, who had been a constant threat, crossed for his side’s eighth try before Russia center Alexei Makovetsky took a long pass on the left and went over for Russia’s third try.

Replacement loose forward Alessandro Zanni barged over for Italy’s ninth and final try.

“Our play was not so good tonight but I am glad we scored some tries, they are the first tries for the Russian team at the tournament,” Russian lock Alexander Voitov said.

“It’s a tough game and each game is new for us and we are very glad to be here.”
