United States forward Bobby Wood is joining Hamburger SV from German second division side Union Berlin.
The Bundesliga side says the 23-year-old Wood has signed a four-year deal through June 2020.
Wood, who was born in Honolulu, has been playing in Germany for nine years. He joined 1860 Munich's youth setup from Irvine Strikers in 2007, going on to score three goals in 50 games for the first team in the second division.
Wood joined Union last summer after half a season on loan at Erzgebirge Aue. He scored 17 goals and set up three more in 30 league games this season for the capital club.
Wood has four goals in 16 appearances for the United States.
