England scored seven tries on their way to securing a historic series victory over Argentina when they beat the Pumas 26-51 in Buenos Aires.
The historic result is follows on from last week's 3-32 victory which makes Stuart Lancaster's England the first English side to win a series in Argentina 2-0.
Bill Beaumont's 1981 England team won one Test and drew the other.
Already without most of their stars due to the Lions tour and several players being rested England were forced into a change just hours before the Test as Christian Wade was called up for the British and Irish Lions tour so he was withdrawn and Jonny May earned his first start.
England outscored their hosts by seven tries to two to earn a fourth straight victory across all venues against Argentina. Two of England's tries were penalty tries as England dominated in the scrums.
Last week England's flyhalf Billy Twelvetrees was called up by the British and Irish Lions so Gloucester's Freddie Burns started the match and scored 19 points including a try.
Two of England's tries were by winger Marland Yarde who was 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 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 left the squad 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 half-time they had built a 27-12 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 27-12 up at the break but Argentina hit back with a score by winger Manual Montero before Rob Webber went over for England.
The home number eight 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 who had named a stronger team this week than last week.
