At 22, he surpassed legendary countryman Rafael Nadal — in the crowd to witness the feat — who was 24 when he did the same. A seventh Slam put him alongside John McEnroe and Mats Wilander and one behind Andre Agassi, and Ivan Lendl. “Lifting the trophy for the first time in Australia was crazy,” Alcaraz said, before writing on a TV camera lens: “Job finished. Four out of four complete.”
He added: “A dream come true. I dreamt about getting an Australian Open and completing the career Grand Slam.”
He paid tribute to Djokovic. “You were talking about how I’m doing the things I am, but what you’re doing is really inspiring, not only for tennis players but athletes around the world.”
It was a first defeat for Djokovic in a Melbourne final, having won all 10 previously.
