Tonga get off the mark with a 45-24 win at the fourth and final attempt, but it's Ireland and South Africa who make it through to the quarter-finals from Pool B.

An improved showing by Romania today, but unfortunately for them they do finish this World Cup with the worst pool stage record of all 20 teams.

Four games, four losses, no points, 32 for, 287 against, a points difference of -255.

This is Tonga's record win at a Rugby World Cup and an exciting game which send them out of the World Cup with pride.

Tonga got off the mark with their first attempt to foray forward, with Prop Ben Tameifuna going on an adventure through the middle and gaining distance while allowing full-back Salesi Piutau to catch up. Piutau did some great work to offload out to the right to onrushing winger Solomone Kata, who collected and crashed over the line.

Minutes later, Tonga continued their early dominance with George Moala bursting through the arms of his tackler Florian Rosu to score on his World Cup debut to make it 14-0 and a perfect start for the islanders.

Alin Conache got the men in yellow on the scoreboard with a penalty, but their spell of momentum was curtailed shortly after when Tonga completely overpowered Romania to the left, forward Sione Talitui brushing off contacts from front row players and assisted winger Afusipa Taumoepeau for a simple score.

Romania did not give up the fight however, and following a cleverly worked line-out they moved the ball through the phases, and number seven Cristi Boboc crashed over to make the game an interesting contest.

The Romanian surge continued after another scrum which Romania dominated, scrum-half Surugiu burst away with impressive pace and power to dive over in his last game of international rugby. 

The teams went in at the break in this closely fought contest 21-17.

Shortly into the second half Tonga got themselves some breathing room as number eight Sione Vailanu touches down Tonga's fourth try for their first bonus point of the tournament. William Havili remained perfect from the tee.

The back and forth continued with Romanian full back Marius Simionescu collecting a clever kick and dotting down a converted try to keep his side within reach with a 4 points deficit.

Tonga started to pull away when, after good probing runs from wings Solomone Kata and Afusipa Taumoepeau, Tonga were in a good position, and the ball was eventually worked to Pita Ahki who had the space to burst over and score.

Tonga dominated the last 20 minutes and never really looked in doubt after Solomone Kata touched down and then the icing on the cake came when replacement Kyren Taumoefolau bursts through with too much pace and power for the yellow shirts to bring the score to 45-24.

An entertaining game and both sides exit stage left from the tournament with their heads held high.
