Serena Williams and Naomi Osaka Offer Lessons Amid Ugly U.S. Open

The boos rained down on the Arthur Ashe Stadium court on late Saturday afternoon, the New York City fans behaving as if the Jets made another crappy draft pick, or the hapless Mets lost yet another miserable game. Not as if the new U.S. Open champion, who's all of 20 years old, was about to receive her trophy for beating the best women's player of all-time.

That champion, Naomi Osaka, should have been smiling from here to her native Japan.
