Joseph "Nana" Gyau, who played for several teams in Baltimore and Washington during the dawning of U.S. pro soccer and became the patriarch of a soccer-playing family with deep local roots, died Thursday in his native Ghana. He was 78. The cause of death was colon cancer, said his son, Phillip, a former U.S. national team player and the current coach of the Howard University men's team. Gyau's grandson and namesake, Joe, plays for Borussia Dortmund in the German Bundesliga. His granddaughter, Mia, is a member of the U.S. under-18 women's national team. As a member of the Ghanaian national team, Gyau won consecutive African Nations Cup titles in 1963 and 1965 and played in the 1964 Olympics in Tokyo. In 1968, Gyau moved to the United States to play for the Washington Whips in the North American Soccer League's inaugural season. He also played for the Washington Darts, Washington Diplomats and Baltimore Bays. He earned a degree from Maryland, operated banks and businesses, and oversaw a local referees association.
