Osaka beats Serena to win first Grand Slam title

Naomi Osaka became the first Japanese player to ever win a Grand Slam singles title when she beat Serena Williams 6-2 6-4 in in a controversial U.S. Open final on Saturday with Serena suffering a meltdown after being handed a game penalty. 

Osaka, 20, prevailed in the first major final of her career, thus preventing Williams from winning a record-equalling 24th Grand Slam title.

Williams was given a game penalty during the second set after a row erupted with umpire Carlos Ramos, who handed the American a code violation for illegal on-court coaching.

With Osaka in control of the match, chair umpire Carlos Ramos sent Williams into a rage when he handed the 23-time Grand Slam champion a game penalty for a string of bad behavior, including a coaching violation and verbal and racket abuse. 

Williams then launched a verbal attack on Ramos, demanding everything from an apology to accusing him of being a thief. 

The game penalty put Osaka 5-3 up in second set and the 20-year-old Japanese kept her cool to pull off a historic win.
