## Notable stories
### Women's singles final

Naomi Osaka defeated Serena Williams in the final, 6–2, 6–4. During the final, Williams received three code violations, the second coming with a point penalty and the third with a game penalty. The issue started during the second set when chair umpire Carlos Ramos cited Serena for a signal that was sent from her coach. Serena said she was unaware of the signal and verbally sparred with Ramos, saying "I don't cheat to win. I'd rather lose." After a mistake later in the second set, Serena smashed her racket into the court. This led to her second code violation, which Serena found out about upon attempting to serve and which increased the dispute between Serena and Ramos. At this point, referring to the first violation for coaching, Serena stated "You owe me an apology. I have never cheated in my life." During the change at the 3–4 mark, a further discussion between Serena and Ramos broke down leading Serena to call Ramos both "a liar" and "a thief" for issuing the point penalty. As both players were concluding the changeover and getting set, Ramos issued Serena her third code violation, this time for verbal abuse. This led to confusion from both players who did not appear to hear the announcement, which Ramos explained to both after summoning them over to his seat. At this point, US Open referee, Brian Earley, and WTA supervisor, Donna Kelso, were summoned to the court due to the dispute. A four-minute delay occurred due to a discussion between Serena, Earley, and Kelso regarding the issues. After the delay, Serena won the next game before Osaka won the set and match.

† Serena Williams was ranked 26 on the day when seeds were announced. Nevertheless, she was deemed a special case and seeded 17th by the organizers because she missed a significant portion of the last 12-month period due to pregnancy and maternity. ‡ The player did not qualify for the tournament in 2017. Accordingly, points for her 16th best result are deducted instead.
