Aryna Sabalenka swats aside Ella Seidel at Australian Open

Aryna Sabalenka began the defence of her Australian Open title with a 53-minute drubbing of German teenager Ella Seidel.

Sabalenka dropped only 10 points in the first set and had two match points for a double bagel before completing a 6-0 6-1 victory on Rod Laver Arena.

"I’m super happy to be back in Melbourne," said the Belarusian, who lifted her first slam silverware 12 months ago. "Last time I had incredible memories from here, unforgettable I would say. It feels so great to be back and feel the support."

Caroline Wozniacki’s first match at Melbourne Park for four years ended prematurely when opponent Magda Linette, a semi-finalist here last year, withdrew trailing 6-2 2-0.

Wozniacki won her only grand slam title in Australia in 2018 and retired following a third-round loss two years later before having two children and then coming out of retirement last summer.

"I feel very comfortable playing here," said the Dane. "I feel comfortable with the ball. I feel very just thrilled to be here. Immediately when I stepped foot on these courts, in this arena, I felt right at home. I think it’s a special place for me and always will be."

The 22-year-old, who first reached the fourth round here five years ago, did not pick up a racket for four months but has returned rejuvenated and pulled off the upset of the day by defeating 13th seed Liudmila Samsonova 6-3 6-4.

"I’m just here for the journey right now and
