Immediately after, Serena was levied upon a game penalty for "verbal abuse" on the umpire, which put Osaka at the brink of her first Grand Slam title.
The editorial argued that the cartoon was merely another piece from Knight that targeted the powerful.
"If the self-appointed censors of Mark Knight get their way on his Serena Williams cartoon, our new politically correct life will be very tiresome indeed", another passage from the cover reads.
But the cartoon keeps bringing criticism, most notably online. "The world has just gone insane", he added.
Serena had received a warning, a point penalty, and a game penalty after an outburst that saw her call the umpire Carlos Ramos a thief. She added that Ramos could have prevented the incident with clear communication.
Over the course of the fortnight, Osaka defeated Laura Siegemund, Julia Glushko, Aliaksandra Sasnovich, Aryna Sabalenka, Lesia Tsurenko and 2017 US Open runner-up Madison Keys to claim her place in the final.
Over the past 20 years, male players have been far more likely to be fined for misdemeanours than their female counterparts.
Strong winds, heavy rains to hit North Carolina on Friday
Colgate, a Patriot League program from NY , had hotel rooms and meal plans locked down for the trip to Greenville, South Carolina. Some of the few people still left in Nags Head on the Outer Banks took photos of angry waves topped with white froth.
"I'm here fighting for women's rights and women's equality", Williams said at a news conference after the match.
"This despicable cartoon tried and failed to diminish the greatness & grace of @serenawilliams". Advertising and sponsorship specialists predict a lot of such opportunities lie ahead for Osaka, who was born in Japan to a Haitian father and a Japanese mother and raised mostly in the U.S.
On Monday the cartoon by Mark Knight, who has since deleted his Twitter account, was called racist, as it depicted Williams with stereotypically oversized features, throwing a tantrum.
"This isn't satire - it is disgusting racist caricature", Twitter user Rose Weber wrote on Tuesday.
Carlos Ramos, the umpire at the heart of the astonishing controversy during the women's US Open final at Flushing Meadows on Saturday evening, returns to work today, as he sits in the high chair for the Davis Cup match between Croatia and the United States in Zadar. He did what he had to do in that match because she overstepped the limit.
The cartoon has been blasted by numerous athletes, celebrities, journalists and activists.
The cartoon attracted anger over Knight's depiction of Williams as a large woman with oversized lips, calling it a stereotypical portrayal of black women.
However, the tennis champion's husband, Alexis Ohanian has broken his silence to slam Mark Knight's drawing as "blatantly racist and misogynistic".
