Who? Pastrana is an Argentine who has refereed around the globe including in New Zealand, South Africa and Australia, at junior world championships and as an assistant in Super 15.
With James Leckie, Jason Jaftha, Rohan Hoffman, and Nick Briant from New Zealand, Pastrana is stepping out into the eye of the public and players.
Sanzar's intentions are decent and progressive. They need to encourage and introduce as many officials as they can to a game which is becoming increasingly awkward to judge.
The physical demands are severe enough with referees running about 7km in matches while being expected to keep an exact eye on 30 players trying to take advantage of a myriad complicated laws.
They have to pass levels on their speed, shuttle runs, yo-yo tests and repeat sprinting ability while also achieving certain levels of body fat.
That's just a start. Like players, referees have to be able to go to work, perhaps in front of 50,000 crowds, and then endure whatever observations about their performance come through public forums.
Checks for body fat should have an asterisk about a thick skin being mandatory.
Some Super 15 coaching staffs are perplexed already by the difference in rulings they have seen applied across the tournament.
They watch players get away with acts which are then penalised in another country. If coaches are scratching their heads, how do Sanzar men like referees boss Lyndon Bray expect the public to understand the game?
Officials are allowed to go back a few phases to assess and review their ideas.
The sooner they are hooked up to the public address system at grounds to connect with the spectators and explain their decisions, the better.
Sky subscribers get the benefit; so should those who brave the elements and the vagaries of rugby's rulings.
