Rybakina, Gauff, Osaka Reach Canadian Open Quarterfinals in Toronto

Tennis is a sport where two players hit a ball back and forth over a net.

In Toronto, Canada, some of the best women tennis players in the world are playing in a big tournament called the Canadian Open.

One of the best players, Elena Rybakina, was very close to losing her match.

She was behind 0-3 in the last set, which meant she was in big trouble.

But she did not give up and came back to win, so she gets to keep playing.

Naomi Osaka, who has won four of the biggest tennis championships ever, also won her match.

Coco Gauff, a young American star, won her match very easily and has not lost any set in the whole tournament.

Now, Rybakina will play Osaka, and Gauff will play Belinda Bencic.

The winners of those matches will be one step closer to winning the Canadian Open trophy.
