Buenos Aires - Freddie Burns scored 19 points as England beat Argentina 51-26 in the second Test here on Saturday.
Fly-half Burns helped Stuart Lancaster's team to become the first side from England to win a test series in Argentina 2-0.
They scored seven tries with two earned by the pack forcing penalty tries and two for winger Marland Yarde on his test debut with Kyle Eastmond also scoring in his first international.
The win wraps up four out of four for Lancaster's side who rested five senior internationals and had their British and Irish Lions missing from games against the Barbarians, a South American XV and two tests against Argentina.
Burns, on duty with Owen Farrell in Australia with the Lions, did his best to earn an Elite Player Squad place when Lancaster announces his 33 man party in August and several other youngsters gave the head coach food for thought.
Eastmond and Yarde made major contributions as England made light of the absence of Christian Wade who was also called up by the Lions earlier in the day.
But they were made to work hard by a determined Argentina team who did not perform in the first half of the previous test.
Lancaster's side were comfortable 32-3 winners in Salta last week and by halftime they had built a 25-12 lead thanks mostly to two penalty tries earned by their pack.
Trailing 12-6 with 31 minutes gone they forced the Argentinean scrum into conceding five points with a big drive and Burns extended their lead when he stretched over on 40 minutes with two defenders handing onto him.
Just before the break England captain Tom Wood backed his forwards again when the Pumas conceded a penalty near the line and referee Nigel Owens gave them a second penalty try after another huge drive.
That put England 25-12 up at the break but Argentina hit back with a score by winger Manual Montero before Rob Webber went over for England.
The home No 8 Tomas Leonardi grabbed another score but when Eastmond went through three defenders on his way to the line the game was sealed.
There was time for Yarde to add his second as England ran out winners against an Argentinean team weakened by the loss of many of their European-based players.
