NEW YORK (AP) — Naomi Osaka’s title defense at the U.S. Open is over after a third-round loss to Canadian teenager Leylah Fernandez. Osaka served for the victory late in the second set but got broken there and then lost her composure in the three-set defeat. She repeatedly tossed her racket and later was warned by the chair umpire after hitting a ball into the stands at Arthur Ashe Stadium. By the end, she heard some boos from the fans for taking too long between points. Osaka is a four-time Grand Slam champion and Fernandez never has been this far at a Grand Slam tournament.
