(Washington Post) Stung by what they perceive as a lack of institutional support for the chair umpire who gave Serena Williams a game penalty late in the U.S. Open women’s final, which set off a firestorm of criticism, other umpires are reportedly discussing the possibility of boycotting her matches. Top umpires are also considering the formation of a union, according to a report Tuesday, in part because they are not allowed to discuss specific matches.

Williams was free to speak her mind after losing, 6-2, 6-4, Saturday to Japan’s Naomi Osaka, and she accused chair umpire Carlos Ramos of sexism. He had given her a warning for coaching, then a point penalty for smashing her racket and, after she repeatedly expressed frustration, including calling him a “thief,” Ramos levied the game penalty for verbal abuse.
