Australia crushed a lamentable England by an innings and 122 runs in a one-off pink ball Test Saturday to complete a historic women's Ashes whitewash. In the first women's Test at the Melbourne Cricket Ground since 1949, the hosts wrapped up victory within three days to culminate a horror tour by the visitors. Australia were in a class of their own all series, reinforcing the chasm between the two sides. They won all three ODIs, three T20s along with the sole Test that comprised the multi-format Ashes, which has been points-based since 2013 -- two for a white-ball win and four for a Test. It was the first time either side has scored a whitewash, ensuring the Ashes stayed firmly in the hands of Australia, which regained them on English soil in 2015 and has retained a tight grip ever since. England arrived in high spirits after winning six of seven matches on their all-format tour of South Africa last month. But they were methodically worn down by an Australian side with far greater strength in depth. After being dismissed for 170 in Melbourne, England dropped eight catches and missed a stumping on a shambolic day two. It allowed the hosts to compile 440 on the back of Annabel Sutherland's majestic 163 and Beth Mooney's gritty 106.
