Jannik Sinner defeated Alex De Minaur 7-5 6-2 in the semi-final of the ATP Tour Finals on hard court, a result that confirmed pre-match odds favouring the Italian top seed. De Minaur, competing as a significant underdog at 8.53, offered modest resistance in the opening set before Sinner's superior court control and consistency asserted itself decisively in the second. The scoreline reflects a commanding performance from Sinner, who controlled the rhythm throughout and capitalised on De Minaur's inability to sustain pressure during crucial moments. The victory advances Sinner to the tournament final, reinforcing his status as the year's dominant hard-court performer and extending his record against the Australian.
