Badosa, Tomljanovic out of Australian Open with injuries

Spaniard Badosa, who reached the fourth round at Melbourne Park last year, withdrew from her Adelaide International 2 semi-final against Daria Kasatkina on Friday after picking up the injury in the previous round.

"Bad news...During the quarter-final match in Adelaide, I hurt myself and after receiving the results I will have to be out a few weeks," Badosa tweeted.

"Sad to miss Australian Open this year, really going to miss it. I will do everything I can to return as soon as possible."

Ajla Tomljanovic has also withdrawn from the year's first Grand Slam, which starts on Monday, after the local hope sustained a knee injury at the season-opening United Cup mixed team tournament.

"I've done absolutely everything in my power to get healthy but just ran out of time to heal and be 100% ready to compete at a high level," Tomljanovic tweeted.

"It's been a very tough decision to make but I have to listen to my body."
