Rinderknech Stuns Zverev; Tien Upsets Norrie

Arthur Rinderknech stunned third-seeded Alexander Zverev 4-6, 6-3, 6-2 in the Shanghai Masters third round, ending Zverev's run after the German had earlier battled a painful toe/foot issue following his win over Valentin Royer. Rinderknech, ranked 54th and enjoying a career-best year, will next face Jiri Lehecka. American Learner Tien upset Britain's Cameron Norrie 7-6(4), 6-3 to set up a meeting with Daniil Medvedev. Alex de Minaur beat Kamil Majchrzak 6-1, 7-5 to reach the fourth round, while Jiri Lehecka, Nuno Borges and Felix Auger-Aliassime also advanced. Stifling humidity has affected players throughout the event, prompting mid-match shoe changes and contributing to physical problems and retirements, and Novak Djokovic is now the highest-ranked player remaining.
