Carlos Alcaraz says he did not bend the rules by taking a medical timeout during his Australian Open semi-final against Alexander Zverev - who suggested the Spaniard had benefited from favouritism.
Spain's Alcaraz seemed to be cramping at 5-4 in the third set and was allowed to see the physio, even though Grand Slam rules say players are not allowed medical timeouts for muscle spasms.
Players can take a three-minute timeout for physical injuries or illness but not for cramping, which is regarded as a conditioning problem rather than a medical issue.
Alcaraz, 22, went on to lose the set before winning a five-hour classic 6-4 7-6 (7-5) 6-7 (3-7) 6-7 (4-7) 7-5 as the Australian Open finally sparked into life.
