Just twenty years old, she wiped the floor with her idol, Serena Williams.
She showed considerable emotional maturity during the match for one so young - keeping her composure and concentration throughout.
She's quite affable - at the end when she got the trophy she basically apologised for winning!
She's a very talented athlete. This match reminded me a little of the 2001 Wimbledon match between then-defending champion Pete Sampras and some young player called Roger Federer.
I strongly believe this US Open title won't be Osaka's last Grand Slam win.
Well done Naomi Osaka!
