Zverev and Alcaraz Set Vienna Semifinal Showdowns

Zverev reached the semifinals with a 6-0, 6-2 win over an ailing Fery; Alcaraz beat Paul and will face Medvedev, who defeated Mannarino 6-2, 6-3. Medvedev also clinched his seventh ATP Finals appearance. The claim that Zverev has clinched world No. 1 remains unverified.
