NEW YORK (CNN) -- Naomi Osaka won her first grand slam title Saturday, beating Serena Williams in a controversial US Open final that saw the American docked a game after calling the umpire a "thief."
Osaka prevailed against her idol 6-2 6-4 in New York to deny Williams a record 24th major and become the first Japanese player to ever win a grand slam singles title.
Osaka indeed made history for Japan but the final will be remembered as much -- if not more -- for Williams clashing with chair umpire Carlos Ramos.
Ramos first gave Williams a code violation warning for coaching in the second game of the second set. Williams then approached the net and told Ramos: "I don't cheat. I'd rather lose. Every time I play here I have problems."
Williams may have been referring to 2009 at the US Open when she received a point penalty against Kim Clijsters in the semifinals -- she was deemed to have verbally abused a linesperson -- and was called for hindrance during a point in the 2011 final against Sam Stosur.
Williams later got a point penalty Saturday for cracking her racket and then was docked a game, to trail 5-3, for what Ramos deemed to be verbal abuse towards him.
Williams had called Ramos a "thief" during the changeover at 3-4.
Osaka sealed her first major with a thumping serve out wide.
