16 seed - won the round of 16 match 6-1, 4-6, 6-4 to advance to her third consecutive Australian Open quarterfinals.
It was a match that had everything: umpire controversy, injury twists and stunning rollercoaster momentum shifts.
The Romanian is now on top of the women's world ranking with the American tennis star down in 16th place.
"I feel like that had to be a factor". I just need to keep taking it one match at a time.
Some pointed out that the mishap was prophetic, as Williams eventually beat Halep and eliminated her from the battle for the Grand Slam title. But, if I had the chance to talk to Serena, this is what I'd say: "At least your mum actually shows up!" She instead declared she was helpless to try and stop the red-hot Pliskova's six-game run.
Coming into the match as one of the biggest servers in the women's game, Pliskova managed three aces in the match while the Japanese reeled off 15, often coming up with unreturned serves to win the crucial points.
"I think she just played well on my serve after that point".
"There are moments in the match where I thought, like, this is getting really close". Speaking in a conference call, Mouratoglou said: "I think she's fitter than she was past year because even though she really made a lot of effort to come back in shape, I don't think she had enough time".
Serena and Pliskova have met only thrice before with Serena winning two out of the three matches.
Serving at 5-1, the linesman's call triggered an epic series of blunders and drama.
A eighth triumph in Melbourne would have seen her move level with the 44-year record set by Margaret Court - but she lost in remarkable circumstances next door to the stadium named after the Australian. It's Osaka's your coverage that gives her the edge in this match, even if the small h2h sample size doesn't suggest it.
"It was tough because she [Williams] was really playing well I didn't have many chances in the third set", she continued.
The outbursts by Williams during that match reminded many of her tirade during the 2009 U.S. Open, one that began when she was called for a foot fault.
A number of people questioned the timing of the foot fault, including commentator Mary Joe Fernandez. In a vicious Australian Open encounter that lasted a little less than two hours, it was the 37-year-old American, Serena, who had the last laugh.
"I just think she was just nailing and hitting shots".
"That's how it is in tennis".
She said the big-serving Czech seventh seed was simply too good on the crunch points and she had learned lessons from the experience. "I think it's going to be the best comeback ever so far in my life".
I picked it up and said, "Oh, are you enjoying this?" At that point I'm just trying to think, 'okay, win some points, win this game'. I was struggling a bit on that side against the wind. "It doesn't matter. You just have to know what you're doing and she does". She said, "Hmmm, I don't have much time for reading these days".
Only then did Williams get going.
Muslim community targeted in foiled attack wants justice
In March 2015, authorities arrested a Tennessee man named Robert Doggart for plotting an Islamophobic attack on the compound. The three adults arrested were 20-year-old Brian Colaneri, 18-year-old Andrew Crysel and 19-year-old Vincent Vetromile.
