From the USTA: (February 4, 2015) Coco Vandeweghe and Taylor Townsend will replace Madison Keys and Varvara Lepchenko on the U.S. Fed Cup Team roster for the World Group II First Round in Buenos Aires, Argentina. Keys suffered a leg injury in the Australian Open en route to her first career Grand Slam semifinal, while Lepchenko suffered an illness after competing in Australia and is still recovering.
Vandeweghe, 23, is ranked a career-high No. 32 in the world after a strong start to the year, where she reached the third round of the Australian Open and the quarterfinals of the WTA event in Auckland, New Zealand. Vandeweghe made her only appearance on the U.S. Fed Cup Team in the 2010 World Group Final against Italy in San Diego. Townsend, 18, is ranked No. 96 in the world and is making her Fed Cup debut. Vandeweghe and Townsend join Serena Williams and Venus Williams, who were named to the U.S. team last week by U.S. Fed Cup Captain Mary Joe Fernandez.
The United States will face Argentina on an outdoor red clay court at the Pilara Tennis Club in Buenos Aires, February 7-8. The winner of this tie advances to the World Group Playoff, held April 18-19, to compete for a spot in the 2016 World Group. This will mark the fifth matchup between the U.S. and Argentina in Fed Cup competition, where the United States holds a 3-1 record over Argentina.
