Naomi Osaka's short-term future appears away from the tennis court after the tearful former world number one said she plans to "take a break from playing for a while" following her shock US Open elimination. Osaka's US Open title defence came to a remarkable end after imploding in Friday's surprise 5-7 7-6 (7-2) 6-4 loss to teenage sensation Leylah Fernandez. Up a set and serving for the match at 6-5 on Arthur Ashe Stadium, Osaka lost her cool and composure after throwing her racquet three times in an unsuccessful second-set tie-break. Amid boos in New York, Osaka was also warned after hitting a ball into the crowd and while the four-time major champion tried to dig herself out of a hole, she crashed out in incredible fashion.
