Though the Saints' summer signing didn't feature for a third cap in the 27-26 win over Japan, he had been involved in each of the previous two wins as the Samoans maintained their 100 percent record in Tokyo and took the title for a second time in three years.
Meanwhile in South Africa, it was a weekend that started badly for the Saints' England representatives, Phil Dowson forced to pull out of the matchday 22 ahead of the second Test after tweaking a hamstring and it wouldn't get much better for Stuart Lancaster's men in Johannesburg.
Despite a valiant second half comeback - Ben Foden, Dylan Hartley and Lee Dickson all involved - an early Springbok blitz proved enough to see them run out 36-27 victors, securing a series win in the process. The final Saint involved internationally over the weekend was Ben Nutley, who came off the bench during England Under-20s' 5th-8th place playoff defeat to Ireland at the Junior World Cup.
The sextet, including Paul Doran Jones, will have further chances to pull on the white of England - the senior side facing a SA Barbaians North side tomorrow ahead of the third and final Test in Port Elizabeth on Saturday. England Under-20s conclude their Junior RWC Campaign against their Australian counterparts on Friday afternoon.
Finally, Pisi will also be hoping to capture another Samoan cap as the islanders take on Scotland in Apia in the early hours of Saturday morning.
