Match recap

Sebastian Baez defeated Arthur Rinderknech 7(8)-6(6), 2-6, 6-4 in the R16 of the Austrian Open Kitzbühel 2026.

The biggest points fell to Baez, and almost nothing else did. Arthur Rinderknech out-aced Sebastian Baez 21-2, took 102 of 199 points and converted 3 of 4 break chances against the Argentine's 2 of 6, yet won just 46 percent behind a second serve that leaked six double faults. The decisive swing came in game 7 of the third, a break for 4-3 that held, and the upset is one of seeding rather than expectation — the market had priced the clay-stronger Baez at 52 percent. Two hours and 24 minutes in, it was over, sending the 25-year-old into the Kitzbühel Open quarterfinals and the No. 3 seed out a day before his 31st birthday.
