Despite attempting to play down the issue, Alcaraz glugging pickle juice – an acidic liquid found to stop cramping 40% faster than drinking water – was a sure sign that it was an issue.
Germany’s Zverev was furious as he remonstrated with the match supervisor, accusing the officials of giving Alcaraz preferential treatment.
Afterwards, third seed Zverev reiterated he “did not like” the decision before adopting a more conciliatory tone.
“To be honest, I don’t want to talk about this right now, because I think this is one of the best battles there ever was in Australia. It doesn’t deserve to be the topic now,” said the 28-year-old, whose quest for a maiden Grand Slam title continues.
Top seed Alcaraz said quitting the match never entered his head, adding: “I just hate giving up”.
Alcaraz has a tattoo on his wrist which is a tribute to the family phrase coined by his grandad – ‘Cabeza, corazón y cojones’.
If you don’t understand Spanish it is perhaps better you search online for the literal translation of a motto which Alcaraz abides by.
In summary, the phrase means the ability to show head, heart and courage in times of difficulty.
Once again, Alcaraz showed all three qualities when he dipped deep into his reserves to beat Zverev and reach a first Australian Open final.
“When I was younger, there were a lot of matches that I just didn’t want to fight any more or I gave up. Then I got mature,” he said.
“I hate that feeling [of giving up] after all.
“Every step more, every one second more of suffering, one second more of fighting is always worth it.
“That’s why I just fight until the last ball and always believe that I can come back in every situation.”
