World number one Carlos Alcaraz ruled out of Australian Open 2023

World number one Carlos Alcaraz has been ruled out of Australian Open 2023 due to a right leg injury. He tweeted, "I picked up an injury through a chance, unnatural movement in training. This time it's...semimembranosus muscle in my right leg." Alcaraz would've held top seed at a Grand Slam for the first time if he would've played Australian Open.
