Steffi Graf once called out Martina Hingis for her controversial conduct in their 1999 French Open final. Hingis' behavior also didn't appeal to the crowd, as she was subjected to loud jeers and boos.
Graf won her 22nd and final Grand Slam title at the 1999 French Open, securing a hard-fought 4-6, 7-5, 6-2 win over Hingis in the final. Beyond the German's impressive victory, the match caught attention for Hingis' controversial actions on the court.
The then-18-year-old, who was attempting to complete the career Grand Slam in singles, made a strong start, clinching the opener 6-4 and taking a 2-0 lead in the second set.
However, the match took a contentious turn when Hingis disputed a line call, despite the umpire upholding the call after reviewing the mark. In an unexpected move, the Swiss went over to Steffi Graf's side of the net to argue her claim, resulting in jeers from the spectators and a point penalty from the umpire.
Subsequently, Graf turned the tide, taking the second set 7-5 to force a decider. Hingis further garnered fans' ire when she took a lengthy bathroom break after the opening game of the third set. The atmosphere turned more hostile when the Swiss delivered an underarm serve at match point down at 5-2.
The crowd's hostility got to Martina Hingis after her loss as she rushed off the court in tears. She only returned for the trophy presentation after being convinced by her mother Melanie Molitor.
Following her win, Steffi Graf suggested that Hingis might have placed too much importance on the match.
"It's a game out there, and sometimes I felt it was more than that for her. That's what I didn't really understand, because I mean, she has everything going for her. There will be other times," Steffi Graf was quoted by the Washington Post.
The German also criticized Hingis' behavior during the final, urging the Swiss to be more respectful of her opponents.
"You have to be respectful of your opponent, and sometimes she hasn't been. It is something she really should take a closer look at because we're all out there, trying hard," she added.
