The first Belgian to win a grand slam title, the French Open champion has weaved her brand of attacking tennis to devastating effect this season, winning six titles on hard courts and on clay.
But she will have to be prepared to deal with a hostile reception from the raucous New York crowd, who may want to punish the Belgian for defeating Serena Williams in a controversial semi-final at Roland Garros in June.
If her powerful one-handed backhand shot is on song, Henin-Hardenne could be tough to beat.
