Samoa thrashed Uruguay 56-22 overnight to advance to the World Rugby Under 20 Trophy final against Spain.
The Baby Manu led 24-8 at half-time and ran in seven converted tries in all to finish atop Pool A with three straight wins.
Coach Ramsey Tomokino said it was pleasing to see his players step up in another physical match against the South Americans.
"We knew they had a powerful scrum, we knew they had a strong mauling game but we knew we had to repel that - they shunted us in the first scrum and then we were able to get ascendancy in the game and obviously, once we had taken their scrum away and their maul away, the rest was there for us to take and...pleased with how we played overall - it was a good result and a good win."
Ramsey Tomokino said thankfully the squad came through the match without any injury concerns and is now just 80 minutes away from being promoted back to the elite Under 20 Championship.
"Very pleased with the result - wasn't very pleased with how we finished but I ran alot of changes with still a quarter of the match to go, just to reward guys who had done well, but (with the score at) 56-8 we could start to look ahead to Sunday but we probably made too many changes, lost a bit of momentum but it was great to get the result."
Spain pipped USA 18-16 to join Samoa in the final as Poor B winners, while Fiji finished with a comprehensive 42-22 victory over hosts Zimbabwe.
