Samoa have stuck with a winning combination for the final of the four-nation tournament in South Africa where they are up against their hosts in Pretoria on Saturday.
Coach Stephen Betham on Thursday named the same line-up that eased to a comfortable 39-10 win over Italy in Nelspruit last week for the match-up with the Springboks at Loftus Versfeld.
There is only one change among the substitutes where flanker Alafoti Faosilva replaces Piula Faasalele, who won his first cap off the bench last weekend, a Samoa Rugby Union statement said.
Samoa beat Scotland 27-17 in their first game of the competition in Durban on June 8 and followed that up with five tries against the Italians last Saturday.
Samoa have lost all seven previous tests against South Africa but pushed the Boks close in a 13-5 setback at the 2011 World Cup in New Zealand in their last meeting.
