Tallon Griekspoor Apologizes After Vienna Withdrawal; Alexander Zverev Advances

A back injury forced Griekspoor to withdraw before his Vienna quarterfinal with Zverev, ending a run that included wins over Khachanov and Nakashima in two tiebreaks. “I’m sorry. See you next year, Vienna!” he posted. Zverev advanced by walkover and became the fourth player to book a Turin berth, closing in on Andy Murray’s eight ATP Finals appearances.
