A last-gasp try by Emiliano Boffelli – who plays his club rugby for Edinburgh – gave the hosts the win, who at one stage looked down and out.
We give each Scotland player a mark out of ten for their performance in Santiago del Estero ...
1. Rory Sutherland
Back in the starting line-up in preference to Pierre Schoeman. Was his usual solid and unspectacular self. 6 Photo: Craig Williamson - SNS Group / SRU
2. Ewan Ashman
Marked his first Scotland start with two tries, the second of which was worthy of a winger. A bit wayward with his throwing in, however. 7 Photo: Paul Devlin - SNS Group / SRU
3. Zander Fagerson
Posed a threat in the loose on his 50th appearance and had a hand in Scotland’s fourth try. 6 Photo: Jane Barlow
4. Scott Cummings
Good to see him back in the starting XV after a long spell injured. Strengthens Scotland’s options in second row but lineout was a mixed bag. 6 Photo: PABLO GASPARINI
