Mirra Andreeva train whistle serve

von Felix P: Marta Kostyuk

Mirra Andreeva was about to serve against Marta Kostyuk at Pat Rafter Arena when a train whistle cut through the Brisbane International 2026 quarterfinal, not once, but twice, right as she tossed the ball. The timing was so perfect the crowd lost it, laughing and cheering #MartaKostyuk #Tennis
