Andreescu withdraws from Australian Open

World No.6 Bianca Andreescu has pulled out of the Australian Open due to a knee injury

US Open champion Bianca Andreescu has withdrawn from the Australian Open after failing to recover from a knee injury.

Andreescu, the world No.6, had hoped to overcome her injury in time for Melbourne Park after pulling out of the Auckland ASB Classic in December.

The Canadian suffered the injury at the WTA finals in Shenzhen last year.

"The Australian Open is unfortunately too soon in my rehab process and I sadly will not be able to play in it this year," Andreescu said on social media.

"It was a very tough decision to make as I love to play in Melbourne but I have to respect the recuperation plan for my knee and body."

The 19-year-old enjoyed a memorable year in 2019, soaring from No.178 at the start of the year to as high as No.4 in October.

She won her first WTA tour title at Indian Wells, before beating Serena Williams in Toronto and again in New York to clinch her maiden grand slam title.

Officials have also confirmed Richard Gasquet has followed Juan Martin De Potro in withdrawing from the tournament, which begins on January 20.
