Gavrilova v Keys in Fed Cup tie

Brisbane - Russian-born Daria Gavrilova will open Australia's Fed Cup tie with the United States against Madison Keys on Saturday in her debut outing for her adopted country.

The 22-year-old, a breakout star at this year's Australian Open, gets the tie under way on a purpose-built clay court at Pat Rafter Arena for the right to return to the elite World Group.

Fed Cup veteran Samantha Stosur will face Christina McHale in Saturday's other match, with the world number 57 selected despite being ranked lower than compatriot Coco Vandeweghe.

Sunday sees the reverse singles rubbers and the doubles.

Australian captain Alicia Molik has put forward Casey Dellacqua and Stosur in her doubles line-up, while USA skipper Mary Joe Fernandez has opted for the formidable duo of Bethanie Mattek-Sands and Vandeweghe.
