Samoa have run in four tries as they continued their preparations for the Rugby World Cup with a 34-9 bonus-point win over Tonga in the final round of the Pacific Nations Cup in Apia.
Hooker Sama Malolo scored the opening try from close range in a tight first half in Samoa's capital, and three more after the break took the game away from the Tongans.

Lock Miracle Fai'ilagi went over off the back of a rolling maul, centre Duncan Paia'aua grabbed the second and replacement halfback Melani Matavao skipped across the line for the third after a quickly taken penalty in the 63rd minute.
D'Angelo Leuila, who took over as Samoa five-eighth from former Wallabies playmaker Christian Leali'ifano, contributed 14 points from the kicking tee.
"It was a real arm-wrestle in that first half," Samoa skipper Michael Ala'alatoa said.
"We knew the Tongans were going to bring a physical game, but we were able to withstand that pressure in the first half and score some points and build some cohesion in the second."
Tonga, who struggled to get their potent backline moving, had to settle for three penalties.
The victory was Samoa's second in the Pacific Nations Cup after their 24-22 win over Japan in Sapporo last month.
They trail Fiji, who play Japan in Tokyo later on Saturday in the final match of the tournament, by one point in the standings.
