Simpson Clairmonte "Sammy" Guillen (24 September 1924 – 1 March 2013) was one of the few men to have played Test cricket for two countries. He played five Test matches for the West Indies and three for New Zealand in the 1950s, including New Zealand team's first victory, over the West Indies. He sealed the win by affecting the stumping of Alf Valentine in what was his final Test as a New Zealand player.
