==Playing career=+
Bouza made his international test debut at the age of 26 on 8 June 1996 against Uruguay in a 37–18 victory. He missed out on selection for the 1999 Rugby World Cup, but when selected for the 2003 Rugby World Cup he scored four tries in two games and was the only forward in the top ten try scorers. Bouza scored nine test tries in his 38 appearances for Argentina.
He played for Duendes Rugby Club in Rosario, Argentina where he was captain before moving to the English club NEC Harlequins in August 2005 in National Division One. He made only five appearances for the Quins in their promotion winning season.
Director of Rugby Stuart Lancaster said at the time: "Pablo is a vastly experienced international second row who will be a great addition to our squad for next season. I have spoken to Dean Richards, his coach last season, regarding his qualities and he has nothing but praise for him both for his ability and his attitude to the game. He will give us good strength in the second row and I am looking forward to having him in our group."[1]
For the second straight year, Bouza was a member of the team that earned promotion to the Guinness Premiership.
