Griffin commenced playing in 1953 for the Nedlands-Subiaco Lacrosse Club in Western Australia, making his A Grade debut in 1957.

Griffin captained the Australian side at the inaugural World Championship in Toronto, Canada, in 1967, and was selected as Australia's most valuable player for the tournament.

Being able to throw and catch with both hands was unheard of until then, and he also developed a back-hand shot which made for greater depth in play.

American experts described Griffin as the best player in the world, and he was recognised by the US Lacrosse Hall of Fame, Baltimore, following that 1972 tour.
