Cape Town - Argentina have named their team to face the Barbarians at Twickenham on Saturday.
Flanker Pablo Matera will lead Los Pumas, who have blown hot and cold in 2018.
They beat the Springboks and the Wallabies in the Rugby Championship, but then lost all of their matches on their tour to the northern hemisphere.
The Barbarians, who are coached by Springbok mentor Rassie Erasmus, picked 13 Boks in their match-day squad.
The Barbarians are taking on Argentina for the third time in their 128-year history.
The Pumas were beaten 34-22 in Cardiff in 1990 but won the 2015 rematch 49-31. Lood de Jager is the sole survivor from the BaaBaas side that day.
Saturday's clash is scheduled for 16:30 (SA time).
