October 25, 2019 -- Basel, Switzerland

Unfortunately, Roger did not take the court today as his opponent, Stan Wawrinka, had to retire due to an injury.

After an intense 2 and a half hour match against Frances Tiafoe, Stan said it flared up his back injury and took a toll on his body. Clearly disappointed, Stan said, "Not to be able to play this match in Switzerland is very sad. But I need to listen to my body at this point.”

Roger will now face either Tsitsipas or Krajinovic for a spot in the Finals.
