Japan's Yoshihito Nishioka lost to world No. 8 Holger Rune of Denmark in the men's singles first round of the Australian Open tennis tournament Tuesday.
Rune won 6-2, 4-6, 7-6(3), 6-4 at Melbourne Park's Rod Laver Arena. With Nishioka's loss, all seven Japanese have been eliminated from singles play.
Former world No. 1 Naomi Osaka, who is coming back from giving birth to her first child, lost a day earlier to France's Caroline Garcia.
Rune converted three of 11 break points, while the left-handed Nishioka took only one of his seven opportunities to break serve.
The 20-year-old Danish star hit 17 aces to Nishioka's four.
Nishioka had come to the first Grand Slam event of the year after missing a pair of tune-up events because of left shoulder and left leg injuries sustained late last year.
"I haven't been able to play enough, so it can't be helped," Nishioka said. "I made a lot of easy mistakes (in the third-set tiebreak). I'm recovering from injuries. I had some positives."
In other first-round action Tuesday, women's top seed Iga Swiatek of Poland defeated American Sofia Kenin 7-6(2), 6-2.
