"Sometimes I was even smiling on the court", said the Russian, who will rise to No. 11 in the world if she loses the final, and No. 9 if she wins it.
"I'm a bit exhausted", she said after the 2hr 50min encounter.
"She was playing really good, honestly". Remember, her breakthrough run at Flushing Meadows came to a stunning end when she failed to hold a 5-1 third-set lead against Madison Keys.
Williams defeated younger sister Serena in the third round, one of four straight-set victories she's had so far. 'She is one of the best servers on tour and I was able to break her quite a few times so I am really happy about that. "So I just tried to be a little bit annoying and return a lot", explained Osaka.
"She was better. She was more prepared and she was ready to play and ready to win the match. She's hitting her forehand, backhand, so she's really tough".
Daria Kasatkina, of Russian Federation, reacts after defeating Venus Williams, of the United States, 4-6, 6-4. But will it be the impressive retrieving skills of Kasatkina or the power of Osaka that triumphs?
Stenson leads while Tiger surges at Bay Hill
Rose's playing partner Woods also clawed his way back into the tournament with a 69 and at seven under lurks ominously. Rory McIlroy was slowed again, this time with a pair of bogeys to start his back nine, though he could accept a 70.
Ben Woodburn and Harry Wilson named in Wales squad
Even though it was at U21 level, I've still played against other countries and against some of the best up and coming players. Giggs's side will take on China and then Uruguay or Czech Republic in the China Cup during the upcoming global break.
RE: Audi to launch Tesla rivalling e-tron GT
Audi will build a four-door electric sports vehicle in Germany starting in 2020, the brand's CEO confirmed. Production will start early in the coming decade at the Bollinger Hofe site near Neckarsulm.
She was broken to open the second set and again in the fifth game, giving Osaka a 4-1 lead on her forehand victor down the line.
Until Indian Wells, Osaka had made it past the quarterfinals at a WTA event just once, when she was runner-up in Tokyo 18 months ago.
However, it wasn't meant to be as Osaka comfortably served out the match after an hour and 10-minutes, losing just three points on serve throughout the second set, concluded with a nice and warm hug at the net while the Japanese, with her humorous character, gave what she called the "worst" acceptance speech during the trophy ceremony which left the crowd in laughter.
Then she won the next two games and the biggest match of her career, 4-6, 6-4, 7-5. Interestingly, this was the Japanese's first singles title of any kind, and she has not triumphed on the ITF level either. A victory in Sunday's final would move her into the top 10.
It could not be a bigger contrast from the final line-up at the first and biggest Premier Mandatory tournament of the year in Indian Wells.
At the age of 29, Del Potro has finally ended his long wait for a first ATP Masters 1000 title.
Next up for Federer is Borna Coric of Croatia, who upset No. 7 seed Kevin Anderson 2-6, 6-4, 7-6 (3) for his first win in four tries against the South African.
