Naomi Osaka, 20 years old, just became the first player from Japan to win a Grand Slam.
Yet rather than cheer Osaka, the crowd, the commentators and US Open officials all expressed shock and grief that Serena Williams lost.
Osaka spent what should have been her victory lap in tears. It had been her childhood dream to make it to the US Open and possibly play against Williams, her idol, in the final.
It’s hard to recall a more unsportsmanlike event.
