Defending champion Naomi Osaka didn't make it to the fourth round at the Australian Open.

The four-time major champion was beaten by a 20-year-old American ranked 60th in the world.

If I wanted to give myself a chance, I knew I had to be playing well, and I did that in the second round.

After losing the first set, she knew she had to get more aggressive or she would be out of the tournament.

It worked.

Naomi Osaka lost to the American in the third round of the Australian Open.

In the third set, she served to stay in the match and ended it with an ace. She hit 46 winners to Osaka's 21.

It's the fourth time Osaka has been unable to defend a major title, and the 11th time in a Grand Slam she has been knocked out in the third round.

After winning the title last year, Osaka withdrew from the French Open in the second round and skipped Wimbledon as she took a break for her mental health. After an early loss at the US Open, she took an extended break and arrived at the year's first major with a seeding of 13

Before she had a chance to analyze both players she might meet next, a question was posed to her son about the two-time Australian Open champion's third-round performance.

The five-year-old, wearing his sunglasses in the news conference room and sitting on his mother's knee, responded succinctly: " Awesome!"

She listed the positives from her perspective after thanking her son. I could apply a lot of pressure and bring point after point. Taking control of the court.

She will play Barbora Krejcikova, who came back from a set and break down against Jelena Ostapenko to win.

In the last two years, the two-time grand slam winner has lost first-round matches at the hard-court tournament.

The mother of a tennis player is feeling comfortable right now, fulfilling both roles.

"I feel very lucky that I have him here," she said. These moments are priceless for me. To be able to share that with my son is pretty amazing.

The fourth-round lineups were set on Friday and include fifth-seeded Maria Sakkari against 21st-seeded Jessica Pegula and 8th-seeded Paula Badosa against Madison Keys.
