After anger and confusion reigned inside and outside Arthur Ashe Stadium during last year’s women’s singles final at the United States Open, the tournament organizers were convinced that something had to change.
The United States Tennis Association runs the Open, and it will run it differently now, a year after the furor arose as Serena Williams received three code-of-conduct violations from the chair umpire in the second set of her 6-2, 6-4 loss to Naomi Osaka.
About six months after that match, the U.S.T.A. held a two-day conference focused on strengthening officiating and making it more understandable to the audience.
