Trea Turner homered twice to give him a tournament-leading four, and the defending champion United States romped over Cuba 14-2 to reach its second straight World Baseball Classic final. Paul Goldschmidt and Cedric Mullins also homered for the Americans, who scored in seven of eight innings — putting up crooked numbers in five of them. Turner and Goldschmidt had four RBIs each. The U.S. plays Japan or Mexico in Tuesday night’s championship, trying to join the Samurai Warriors as the only nations to win the title twice. Turner, hitting No. 9 in the batting order, has a tournament-leading 10 RBIs.
