BEIJING -- Bianca Andreescu's winning streak is over.

The Canadian lost 5-7, 6-3, 6-4 to world No. 4 Naomi Osaka of Japan in a China Open quarterfinal today, ending Andreescu's win streak at a WTA Tour season-high 17 matches.

Andreescu, ranked sixth in the world, suffered her first loss in nine matches this year against a top-10 opponent.

It also ended Andreescu's run of 13 consecutive wins in three-set matches.

The Andreescu-Osaka match featured the winners of the past three hard-court Grand Slams -- the 19-year-old from Mississauga, Ont., won this year's U.S. Open, while Osaka won the 2019 Australian Open and the 2018 U.S. Open.
