After keeping the Sudamerica XV at arm's length in Montevideo, England put in an impressive first half performance in the intimidating atmosphere of the packed Estadio Padre Ernesto Martearena to rack up a 25-3 lead going into the break.
Three tries were scored in the first half, with another coming after the break, with Lee Dickson providing good tempo at scrum-half and Paul Doran Jones, Ben Foden and Courtney Lawes all seeing action off the bench.
England now head to Buenos Aires for the second test, looking for a first ever series win over the Pumas in Argentina.
Later on Saturday night Samu Manoa earned rave reviews for his performance in the USA's narrow 12-15 loss to Ireland. Despite the loss there were plenty of positives for the Eagles, not least the 20,000-strong crowd in Houston's BBVA Compass Stadium, a record attendance for a rugby match in the United States.
However on Sunday there was disappointment for Alex Day, Danny Hobbs-Awoyemi and the rest of the England Under-20 squad after their 24-31 loss to South Africa in the second round of IRB Junior World Championship matches. England showed plenty of character to twice come back from substantial deficits to earn themselves a losing bonus point, but coaches and players alike will know that there will have to be plenty of improvement for Thursday's final pool match against the USA.
The performance of the weekend belonged to a future Saint, wing George North, who was the star of the show as the British and Irish Lions continued their unbeaten 2013 tour of Australia with a 22-12 win over Queensland. North started on the bench at Brisbane's Suncorp Stadium, but was in action at the end of the first quarter, firstly in the centres and then on the wing.
North has been named in the team that will play NSW/Queensland Combined Country in Newcaslte, New South Wales, on Tuesday, together with fellow future clubmate Alex Corbisiero.
