Novak Djokovic advanced to the Australian Open semi‑final after Lorenzo Musetti retired in the quarter‑final from a muscle injury. Djokovic was leading 6‑4, 6‑3, 1‑3 when Musetti withdrew at 15‑40 in the fifth game of the third set, citing right thigh pain. The Serbian later praised his fair‑play and said the retirement was fortunate. Djokovic also benefited from a prior retirement by Czech player Jakub Mesnik in the round of 16. The next match for Djokovic will be against Italian Jannik Sinner, who defeated American Ben Shelton 6‑3, 6‑4, 6‑4. The semi‑finals will feature Spanish Carlos Alcaraz versus German Alexander Zverev.
