Hometown: Stockbridge, Ga.
This 16-year-old Chicago native, who attends the USTA training center headquarters in Boca Raton, Fla., is the No. 1-ranked junior in the world. With such a ranking comes lofty expectations, but Townsend has thus far been a star on the junior circuit. In January, she took home the singles and doubles junior titles at the 2012 Australian Open, becoming the first American to accomplish the sweep at a Grand Slam since Lindsay Davenport at the 1992 U.S. Open. Townsend followed that up with a singles third-round and doubles semifinal finish at the French Open. She should be able to make good on her goal of cracking the Women's Tennis Association's top 200 by season's end, when she conceivably turns pro.
