Arthur Gea beat Jakub Mensik 7–6(4), 6–4 in Shanghai on October 13. Trailing 0–3 in the first-set tiebreak, he took seven of the next eight points. His first Masters 1000 main draw had become a quarterfinal run.
Gea also matched a powerful server with his own delivery: 39 of 49 first-serve points won and eleven aces to Mensik’s six. He saved a break point while serving at 5–4 in the second set and finished in one hour, 37 minutes.
The tournament reported thirteen wins in his previous fifteen tour-level matches since July. After three-set wins over Jaime Faria and Ugo Humbert, he had beaten Shelton and Mensik in straight sets.
His quarterfinal opponent was Alejandro Davidovich Fokina, who defeated Hubert Hurkacz 1–6, 6–3, 7–6(6), surviving a deciding-set tiebreak for the second match in a row.
