Fellow players have dubbed Bethanie Mattek-Sands the “rock chick” of tennis because of her tattoos and penchant for motorcycles and the fact that she wore a black dress to her wedding. The 26-year-old brings her free-spirited ways to the court, where she wears knee-high socks and black antiglare paint; at the pre-Wimbledon players’ party on June 16, 2011, she wore a dress made out of tennis balls à la Lady Gaga. “Tennis has a reputation as being conservative and uppity, but there are so many girls that have big personalities,” says Mattek-Sands. “I want to be colorful, and I want the younger generation to get into tennis. It’s just me being myself.” And while folks can’t help but talk about her fashion, they should also talk about her game. Previously the third-highest-ranked American on the tour after the Williams sisters, she has surpassed Venus Williams in the rankings (reaching No. 31), and she carried the U.S. Fed Cup team to the 2010 final.
