Burchall's mother was born in Port of Spain, Trinidad.
Kind of like Kevin Pietersen playing for the England cricket team even though he was born in South Africa (his mother was born in England).
I think I read that somewhere. Prior to joining the squad one of the T&T players asked him if he had 'Trini blood' in him and obviously the answer was yes. I think he also realized an England cap wasn't in his future.
