Kellock hails flying Scots
Scotland withstood some intense second-half pressure to secure their first series victory in the southern hemisphere as Jim Hamilton's early try set them on course for victory in the second Test in Mar del Plata.
Hamilton forced the ball over as Scotland took less than three minutes to do what they failed to achieve during their victory last weekend and breach their hosts' line.
Argentina bounced back quickly and Felipe Contepomi kicked two penalties but the home side's poor discipline allowed Scotland to gain control for the rest of the first half, although Dan Parks missed two of three penalty attempts.
The hosts dominated the second half but Scotland restricted them to one penalty goal and Parks extended their precarious lead in the 74th minute with an excellent penalty following a rare foray forward.
The hard-earned triumph in torrential rain secured a third consecutive away victory for Scotland, their best run on the road since 1982, which began in Dublin and continued when Parks kicked all of their points during a 24-16 win in Tucuman.
Captain Alastair Kellock hailed the series victory as the highlight of his international career. "We came over here and we worked incredibly hard," he said. "It's been a huge effort from everybody and a really enjoyable tour.
"We played the conditions exceptionally well, we played the territory well and we took our chances.
"We pinned them back when we needed to and the only time they got their tails up was when they were in our half. When we prevented them from being in there, I thought we were in control."
