Bale was the next to make inroads down the left wing, and striker Sam Vokes was caught slightly on his heels as the Spurs wing-back fired a dangerous low cross across the face of the goal.
Olly Barkley impressed at fly-half and after kicking two early penalties, he fired a pin-point cross-field arrow to Andy Beattie on the wing who had the simple task of touching down.
Nathan Dyer cut inside Lee Naylor from the right-wing and teed-up Emnes but the on-loan Dutchman from Middlesbrough fired his shot at the diving Hudson from 10 yards.
Following good work down the right wing, David Dunn crossed low inside the box to Bentley, who turned and fired lowed through Stephen Kelly's legs inside the near post.
That only fired the Pumas and Serra scored their opening try, after good work in midfield from Martin Gaitan, before opposite wing Carballo bagged his first touch down.
