The Italian needed only 92 minutes on court to defeat the tournament's sixth seed, as the Canadian failed to secure a break against the 24-year-old during the match. This victory means Sinner has now achieved 25 consecutive wins at Masters events, including last year's season-ending Masters, which he won. He has claimed back-to-back Masters titles in Paris, Indian Wells, Miami, and the season-ending Masters in Turin. The second seed of this event has twice been a defeated semifinalist, losing to Stefanos Tsitsipas in 2024 and Casper Ruud in 2023. Sinner will face world number four Alexander Zverev in the semifinals, who battled past Joao Fonseca in the quarterfinals. The 19-year-old Brazilian was playing his first Masters quarterfinal in the Principality and fought hard to push the third seed to a deciding set after a second-set tiebreak. However, the 28-year-old Zverev seized his only break opportunity in the deciding set to go up 4-2, held his serve firmly, and secured a 7-5, 6(3)-7, 6-3 victory. The Italian leads Zverev 8-4 in head-to-head meetings, having won the last seven encounters between the two players. However, they have one win each on clay, with Zverev last defeating him in three sets at the Monte Carlo Masters in 2022. Even more convincing was Carlos Alcaraz. The world number one wrapped up the final match of the day by defeating Alexander Bublik 6-3, 6-0.
