SANTIAGO DEL ESTERO: Emiliano Boffelli scored an 81st minute try as Argentina beat Scotland 34-31 in the third Test on Saturday (Jul 16) to claim the series 2-1.Boffelli, who plays for Scottish club Edinburgh, crossed after the Pumas had trailed by 15 points with half an hour remaining in Santiago del Estero.The hosts claimed the decider after losing last week in Salta but won the opening game in San Salvador de Jujuy on Jul 2.Argentina head coach Michael Cheika made 11 changes to his side and named flanker Pablo Matera as captain with regular skipper Julian Montoya injured.Cheika's Scotland counterpart Gregor Townsend handed full-back Ollie Smith his debut as tight-head prop Zander Fagerson made his 50th appearance for his country.In dry conditions in northern Argentina, 27-year-old Boffelli opened the scoring with a tenth minute penalty from more than 50 metres.Under five minutes later Townsend's side responded as winger Duhan van der Merwe slalomed through the home defence to find his way over.Blair Kinghorn, starting at fly-half with Finn Russell rested for the tour, added the extras to make it 7-3 after a quarter of an hour before the hosts re-took the lead.Kinghorn was beaten in the air before Cheika's side recycled possession and their fly-half Santiago Carreras, set-up by Boffelli, replicated Van der Merwe's feats to cross.The score changed hands again after 25 minutes as Scotland hooker Ewan Ashman found the whiteline from the back of a rolling maul and Kinghorn converted.Boffelli succeeded with a 35th minute penalty after missing another long range effort but the visitors led 14-13 at the break.Scotland extended their advantage four minutes after the interval as Ashman claimed his third try in four Tests after
