Former world number one Naomi Osaka cruised past Danielle Collins in just an hour at the Miami Open to move into the Miami Open semi-finals.
The Japanese four-time Grand Slam champion who lost just three games in the entire match has served 13 aces in a 6-2 6-1 win that lasted exactly an hour.
Australian Open finalist Collins appeared to be struggling with a neck injury throughout the match.
Collins was so hindered by the neck issue that she ended up having to serve underarm in her final service game.
While it was a hugely impressive win for the four-time Grand Slam champion, she was left to worry for her opponent due to the physical issues she was visibly having to contend with.
“I hope she is okay,” she said after the match. “I have actually never seen her do that before so I think it might be pretty serious.
“I am glad I was able to get through easily or, not easily, but just quickly. I focused on hitting a lot of good returns.”
Osaka will play Belinda Bencic of Switzerland in the semi-finals.
“This was my first night match so I didn’t know what the conditions were like but I was fine and the fans were great,” Naomi added.
“I’m glad that, in a way, I don’t have a good ranking, because I’m able to play the matches that I need to play. I feel like I’m the type of person that plays better with more matches, so actually having back-to-back matches benefits me a lot.”
