Novak Djoković defeated Jannik Sinner 3–6, 6–3, 4–6, 6–4, 6–4 in the Australian Open semi-final on hard court on 30 January 2026, in a significant upset given that Sinner entered as the pre-match favourite at odds of 1.07. Djoković, positioned as the underdog at 8.63, recovered from losing the opening set to take control of the contest, securing the second set decisively before weathering Sinner's resistance in the third. The veteran's experience proved decisive in the closing stages, as he claimed the fourth and fifth sets to reach the final. The result underscores Djoković's capacity to deliver in high-pressure moments on his favoured hard court, while Sinner's loss marks a setback in what had been a strong tournament for the younger player.
