London (AFP) - Ireland booked their place in the quarter-finals of the World Cup with an unconvincing 16-9 win over Italy at London's Olympic Stadium on Sunday.The Irish managed just one try, from centre Keith Earls, with fly-half Jonathan Sexton kicking the remainder of their points in a match where they played the closing minutes a man down after flanker Peter O'Mahony was sent to the sin-bin.Ireland's win meant both they and France qualified for the last eight out of Pool D, with their meeting in Cardiff next week deciding which team will top the group.Join the conversation about this story »
