Francisco Olegario Segura Cano, better known as Pancho "Segoo" Segura, was a leading tennis player of the 1940s and 1950s, both as an amateur and as a professional. He was born in Guayaquil, Ecuador, but moved to the United States in 1940. Throughout his amateur career he was listed by the USTA as a "foreign" player resident in the U.S. As a professional player, he was referred to as the "Ecuadorian champ who now lives in New York City". After acquiring U.S. citizenship in 1991 at the age of seventy, Segura was a citizen of both countries.
