DUBAI, United Arab Emirates — Stan Wawrinka advanced to the Dubai Tennis Championships final after Nick Kyrgios of Australia retired during their semifinal with a back injury on Friday.
Wawrinka was leading 6-4, 3-0 at the time.
He will be looking for his second title of the year when he plays either sixth-seeded Feliciano Lopez of Spain or unseeded Marcos Baghdatis of Cyprus.
For the second day in a row, Kyrgios received treatment on his back during a match. On Friday, the physiotherapist came to the court during the seventh game changeover.
Kyrgios is the second significant retirement in two days at Dubai.
