Sinner's victory avenged his recent loss to Rublev and showcased his resilience, as he saved crucial break points and battled through challenging windy conditions. Swiatek's performance was marked by her powerful serve, hitting six aces and breaking serve twice in a match that tested her experience against the young Andreeva. Sinner is set to face Alexander Zverev in the semi-finals, who advanced by defeating Ben Shelton in a rain-interrupted match.
