Justine Henin

Justine Henin won 7 Grand Slam singles titles with arguably the most technically exquisite one-handed backhand in women's tennis history. The Belgian champion dominated clay with 4 French Open titles, including a run where she won 27 consecutive sets on the surface. She spent 117 consecutive weeks at world No. 1, the 7th-longest streak in history, despite standing just 5'6" and weighing 126 lbs. Henin’s 2007 US Open final victory featured a 6-1, 6-3 scoreline that outclassed #8 Svetlana Kuznetsova’s average set score by 3 games. She retired abruptly in 2008 at age 25, but still holds a 82.6% career winning percentage on clay, which is 5% higher than the average of any other top-10 player. Her 2003 Roland Garros title saw her drop only 20 games in the entire tournament, a record low for that decade.
