Rugby-Australia dominate second half for 47-10 win over U.S.

Sept 5 (Reuters) - Australia turned a narrow half-time lead into a comfortable 47-10 victory over the United States in a World Cup warm-up game in Chicago on Saturday. Australia did not look like the number two team in the world in a lacklustre first half and only lead 14-10 at the break before they scored five second-half tries against their mistake-prone opponents at Soldier Field. The result was a far cry from the 74-6 thrashing New Zealand inflicted on the Americans at the same venue last year. Australia start their World Cup in Pool A against Fiji on Sept. 23, while the U.S. begin their Pool B campaign three days earlier against Samoa.
