Andrey Rublev was the defending champion, but lost in the semifinals to Bautista Agut.

This tournament marked the return of former world No. 1 Federer to the tour for the first time since the 2020 Australian Open, due to a pair of knee surgeries since then. His defeat to Basilashvili marked a record-extending 24th and final loss from match point up in his career.
