Williams incurred three different violations over the course of a freakish second set: first for on-court coaching, then smashing her racket in frustration and finally for verbal abuse toward chair umpire Carlos Ramos.
Osaka out-played her childhood hero to become the first Japanese player to win a Grand Slam, but her accomplishment was swamped in the controversy surrounding 23-time Grand Slam champion Williams. However, when Serena saw the new champion crying uncontrollably, she spoke to the crowd and ensured the booing stopped and the attention returned to Osaka.
Since then daily rates have improved, from $350 to $633, but Ings said, in his experience, rates didn't increase for the latter stages of the tournament, including the final.
She tearfully accused Ramos of being a "thief" and angrily demanded an apology from the official.
"Because I'm a woman you're going to do this to me", she fumed on the court and after the match, Williams didn't walk back that charge.More news: Eye of Hurricane Olivia breaking apart

"The WTA believes that there should be no difference in the standards of tolerance provided to the emotions expressed by men vs. women", Simon said in a statement.
The first violation given to Williams was for coaching, which isn't allowed during any men's matches but is permitted on the women's tour except in grand slam tournaments.
The drama started when Ramos handed Williams a coaching violation early in the second set because of hand gestures made from the stands by her coach Patrick Mouratoglou.
U.S. great Billie Jean King addressed both issues, also seeing things Williams's way.
"The WTA supports coaching through its on-court rule, but further review is needed". A line could have been drawn, but when you look at Carlos in this situation, it's a judgment call to give that last penalty because she called him a thief. "Thank you", tweeted the 20-year-old Osaka, who is projected to rise to seventh in the world rankings on Monday.
Simon added: "Yesterday's match showcased one of tennis's new stars as well as one of the greatest players of the game". I think he would have (said that to a male player), I think it's a bond that they have and they way they communicate, and maybe not understanding they can have that same conversation with the women'.
