He took with him rackets, balls and a cellphone loaded with photos and videos of a pro player in action to inspire the youngsters. The player was new U.S. tennis star Frances Tiafoe. The move to encourage young Africans by showing them images of Tiafoe, an American with Sierra Leone heritage, has paid off big time. (Sam Jalloh via AP)
