A gutsy all-round performance from the team, led by captain and player of the match Solofuti Falo, saw Samoa claim their first win by 30 runs over Fiji.
Fiji sent Samoa in to bat and continued their good form with the ball, tying the home team down by taking regular wickets
Lasarusa Veiqaravi (4/22 off 7 overs) had an outstanding game with the ball taking four successive wickets in the middle of the innings.
Sitanisilao Toutai (15 off 87 balls) and number 11 Lester Evile (15* off 22 balls) were the only Samoan batsmen to trouble the scoreboard as they were bowled out for just 110 in 43 overs.
However, Samoa's bowlers were spurred on by a vocal crowd to achieve what they needed to do.
The total appeared to be within reach for Fiji but some poor shot selection combined with tight bowling meant pressure began to mount.
As the wickets began to tumble, Samoa's confidence grew and when the sixth wicket fell with just 51 runs on the board, victory seemed within grasp.
Petero Cabebula (25* off 21 balls) offered some late resistance but in the end ran out of partners.
Falo was exceptional with the ball taking the last three wickets to get his team their first win.
Speaking after the match the Samoa captain was clearly pleased with the result and his team's performance.
"I feel so happy and the people in my country are so happy because this is the first time that we have ever won in the under 19 tournaments," he said.
