Argentina recorded a second victory against the touring NSW Barbarians, outdoing their opponents by 58-12 in chilly conditions in Salta.
Trailing by 32-0 at the break, NSW hit back with tries from flanker Jed Holloway and 18-year-old Randwick playmaker David Horwitz to complete the final leg of their two-match series against Argentina.
The second-half tries were just reward for the young team's perseverance against a vastly more experienced Test team.
Boasting 437 caps in their run-on side, the Pumas superiority quickly showed, as they took the lead by slotting three points before adding a further seven courtesy of a converted try from scrumhalf Martín Landajo after seven minutes.
A drop-goal followed by two further tries, one apiece from wingers Gonzalo Camacho and Juan Imhoff, extended the home side's lead to 25-0 on 30 minutes, before a fourth effort, this time from outside centre Joaquín Tuculet, left them with a comfortable 32-0 advantage at the break.
Boosted by the arrival of fresh legs as coach Michael Cheika made the most of his extended bench, the visitors hit back after just three minutes with a try from young replacement playmaker David Horwitz, who also added the conversion.
Further tries from Pumas breakaway Juan Manuel Leguizamón, Camacho and replacement Horacio Agulla put the result beyond doubt but did nothing to diminish the NSW Barbarians' efforts, as they continued to defend with vigour and attack with ball in hand.
Their passion did result in a second try after 73 minutes, scored by Southern districts flanker Jed Holloway and converted by replacement scrumhalf Brendan McKibbin, shortly after Pumas replacement Pablo Matera had added his side's eighth.
The full-time score at a chilly Padre Ernesto Martearena in Salta was 53-12 in the home side's favour, with the match completing the Pumas preparations for The Rugby Championship which kicks off next weekend when the Pumas take on South Africa and the Wallabies host New Zealand.
