Introduction
Petra Mandula (born 17 January 1978) is a Hungarian former professional tennis player, who represented her native country at the 2000 Summer Olympics in Sydney, Australia; in singles she was eliminated in the first round by fourth seed Conchita Martínez of Spain, in doubles she reached the quarterfinals partnering Katalin Marosi. Four years later, when Athens, Greece hosted the Games, she once again was defeated in the first round, this time by Patty Schnyder of Switzerland.
She reached the quarterfinals at the 2001 French Open as a qualifier, winning seven straight matches and losing to eventual runner-up Kim Clijsters. Two years later, at the 2003 French Open, she almost repeated the feat, losing in the 4th round 7-5 in the third set to Chanda Rubin. Also in 2003, Mandula reached the semifinals of the Australian Open with Emmanuelle Gagliardi, losing to Virginia Ruano Pascual and Paola Suárez.
