Naomi Osaka ended a four-match losing run in unfortunate fashion in Tokyo when opponent Daria Saville retired injured in only the second game of the match.
The Australian’s career has been blighted by injury, including long-term knee and Achilles problems, and it is only this year she has returned to the top 100.
Saville yelped in pain after playing a short forehand and collapsed to the court in distress clutching her left knee. She was able to walk away but did not risk continuing, shaking hands with Osaka after only 11 points.
🇯🇵 @naomiosaka advances to the Tokyo last 16 as Saville is forced to retire through injury with the score at 1-0 in the first set.
