WATCH: World No.3 blows up over 'BS' use of medical timeout by Alcaraz

Alexander Zverev has expressed frustration towards Australian Open tournament officials after world No. 1 Carlos Alcaraz was allowed a medical timeout for a cramp during their semi-final match.

The Spaniard was up two sets to love (6-4, 7-6 (7-5)) before requiring medical attention due to the cramp on several occasions throughout the third set, with a medical timeout being used for it.

This would lead Zverev to express his frustrations towards a tournament official.

"It's unbelievable that he gets treated for cramps; it’s BS," he explained.

“You are protecting these two guys all the time.”

And it would be a sentiment shared with Channel Nine's Jim Courier.

“He is cramping," the American said on commentary.

"This is not an injury, and that is why Zverev is melting down. He is completely right here, Alcaraz has pickle juice in his mouth."

This is also in the ruling within the 2026 Grand Slam Rule Book under the Grand Slam tournament regulations on page 19.

Muscle Cramping: A player may receive treatment for muscle cramping only during the time allotted for change of ends and/or set breaks. Players may not receive a Medical Time-Out for muscle cramping.

But after being just one game away from a maiden Australian Open final, the German held serve and won the third set tie break (7-6 (7-3)) with ease.

Currently, the fourth set remains on serve with Zverev and Alcaraz tied 3-3.

The winner of this match will play either Jannik Sinner or Novak Djokovic for the Norman Brookes Challenge Cup.
