Top-ranked Carlos Alcaraz has pulled out of the Australian Open because of an injured right leg.
The 19-year-old from Spain wrote on social media that he got hurt “through a chance, unnatural movement in training”.
The year’s first Grand Slam tournament begins on January 16 at Melbourne Park. The draw is next Thursday.
Alcaraz won the US Open last September and moved atop the ATP rankings. That allowed him to become the youngest man to finish a season at No 1 since the computerised men’s tennis rankings began a half-century ago.
His rise from No 32 at the end of 2021 also marked the largest single-season jump to No 1.
