Overview

• ATP Officiating said the ‘best effort’ code violation given to Daniil Medvedev in Beijing was issued in error and confirmed no fine will follow.
• Medvedev retired from the China Open semi-final while visibly cramping, with the score 5-7, 7-5, 4-0 to Learner Tien.
• Chair umpire Adel Nour issued the warning during the decider for perceived lack of effort, and supervisor Roland Herfel was called to the court.
• Under ATP rules such a violation can carry a fine of up to roughly $40,000, a penalty removed by the post‑match review.
• Tien advanced to his first ATP Tour final and is set to play Jannik Sinner, as Medvedev’s on‑court protests referenced his recent $42,500 US Open fine.
