2019 Australian Open – Women's Singles
defeated Petra Kvitová 7–6, 5–7, 6–4 in the final to win the Women's Singles tennis title at the 2019 Australian Open. By winning the tournament, Osaka took over the WTA no. 1 singles ranking from Simona Halep and also became the first player since Jennifer Capriati to win their first two Grand Slam titles in consecutive fashion. Eleven players had a theoretical chance of becoming no. 1 at the start of the tournament. In addition to Kvitová and Osaka, Sloane Stephens, Karolína Plíšková, Angelique Kerber, Elina Svitolina, Kiki Bertens, Aryna Sabalenka and Daria Kasatkina were also in contention for the no. 1 ranking at the start of this tournament, but were eliminated from contention as the tournament progressed.
Caroline Wozniacki was the defending champion, but lost in the third round to Maria Sharapova.
Amanda Anisimova became the first player born in the 21st century to advance to the fourth round of a Grand Slam singles tournament. Ashleigh Barty also became the first Australian to reach the quarterfinals since Jelena Dokic in the 2009 Australian Open.
This was the first Australian Open to feature a final set tiebreak. When the score in a final set reaches 6–6, the first player to reach 10 points and be leading by at least 2 points wins the set. Katie Boulter and Ekaterina Makarova became the first players to contest this tiebreak in the main draw, with Boulter emerging victorious.
For the first time since 2009 Wimbledon, all of the top eight seeds reached the third round at a Grand Slam women's singles event.Seeds
