Naomi Osaka, Ashleigh Barty move into 3rd round, potential showdown at Australian Open

MELBOURNE, Australia — For the first set, Naomi Osaka's rediscovered love of the game meant it was anything but fun for Madison Brengle in the second round of the Australian Open.

The defending champion conceded only four points in the first four games Wednesday and rifled forehand winners seemingly at will as she breezed to 6-0 in a mere 20 minutes.

The second set started with Brengle celebrating a service hold like she'd finished a long-distance race, but gradually the No. 54-ranked American ground down Osaka to a stage in the seventh game where she finally converted a break-point opportunity — after missing her first nine chances.

That triggered a change in the former No. 1-ranked Osaka, who responded by breaking back immediately and winning the last nine points to complete a 6-0, 6-4 victory.

She will next face Amanda Anisimova, a 20-year-old American who beat Olympic gold medalist Belinda Bencic 6-2, 7-5. The winner of that is likely to face top-ranked Ash Barty in the fourth round.

Osaka won the Australian Open last year, her fourth Grand Slam title, but then withdrew from the French Open and skipped Wimbledon as she took a break for her mental health. She then was ousted early at the U.S. Open.

After a long off-season to reset, she's unbeaten in five matches in Australia this year.

Asked how she rated her form, Osaka said that's not how she's approaching things.

«Honestly I'm trying not to do that,'' she said in an on-court TV interview. „I'm a bit of a perfectionist. If I compare myself with the past, I'll never be satisfied.

“The goal for me is just to have fun… (and) I think we're accomplishing that.''

Since the draw for the first major of the year was made, a big focus has been on a potential encounter between
