Ireland have continued their unbeaten World Cup campaign with a 50-point win over winless Russia.
Munster fly-half Ronan O'Gara got Ireland off to a fast start following a fifth-minute penalty. He then converted four of five unanswered first-half tries for Declan Kidney's men, scored by Fergus McFadden, Sean O'Brien, Isaac Boss, Keith Earls and Andrew Trimble.
Earls began the second half by adding his second try of the match, allowing O'Gara to kick his fifth conversion.
Russia's Vasily Artemyev responded instantly to put their first points on the board. Denis Simplikevich added a second before the hour, but the Bears couldn't engineer a comeback.
Fullback Rob Kearney, Shane Jennings and Tony Buckley added three more tries to Ireland's total before the end of the match to give them a comfortable win.
Ireland face Italy in their final match in Pool C in Dunedin on Sunday.
