Monica Seles the last title that Seles won before the attack in Hamburg, Germany. On April 30 during a quarterfinal match with Magdalena Maleeva in Hamburg in which Seles was leading, Günter Parche, an obsessed fan of Steffi Graf, ran from the middle of the crowd to the edge of the court during a break between games and stabbed Seles with a boning knife between her shoulder blades, to a depth of 1.5 cm (0.59 inches). She was quickly taken to a hospital. Although her physical injuries took only a few weeks to heal, she did not return to competitive tennis for
Steffi Graf to wear a back brace and was unsure about playing the US Open but elected to play while receiving treatment and stretching for two hours before each match. She made it to the final and took the first set against Sánchez Vicario but lost the next two sets — Sanchez Vicario's last victory over Graf. In the middle of the second set, Graf suffered back spasms while reaching for a ball in the ad court. She took the following nine weeks off, returning only for the Virginia Slims Championships where she lost in straight sets to Pierce in the quarterfinal.
