Naomi Osaka has ended Serena Williams' latest shot at tennis history with a ruthless Australian Open quarter-final victory that has stunned the tennis world.
The Japanese superstar overpowered Williams 6-3 6-4 in 75 minutes to leave the American stranded one grand slam shy of Margaret Court's all-time record of 24 singles majors.

Seeking a fourth major of her own, and second Open crown after reigning in Melbourne in 2019, third-seeded Osaka will play Jennifer Brady in the final after the American downed Czech Karolina Muchova 6-4 3-6 6-4.
The World No.3 seemed a little nervous to begin with as Williams grabbed a service break at the first time of asking to establish an early 2-0 lead.
However, the 23-year-old Japanese star rattled off the next five games in a row to leave Williams and those watching in shock.
Osaka's serve proved too much for Williams to handle, with the Japanese star formidable on her own racquet.
The three-time major winner's powerful groundstrokes also caused nightmares for her American opponent, with commentator Sam Smith declaring Osaka to be the most powerful hitter in women's tennis.
Williams - bidding for a record-equalling 24th grand slam singles title - is used to blowing her opponents off the court.
But it was Osaka that brutally flipped the script with a devastating display against the seven-time Australian Open champion.
While it looked on paper like a routine straight sets win for Osaka, the Japanese star gave fans a scare with a remarkable implosion in the second set.
The World No.3 uncharacteristically gifted Williams a window back into the set with three double faults in the one service game.
That inexplicable mid-set blip helped Williams get back on level terms at 4-4 but any glimmer of hope the American had was quickly extinguished.
Osaka instantly broke back next game to give herself a chance to serve for the match.
