The U.S. Open has fined Serena Williams $10,000 for her tirade directed at a line judge at the end of a semifinal loss to Kim Clijsters.
It’s the maximum on-site fine a Grand Slam tennis tournament can issue for unsportsmanlike conduct.
The U.S. Open said the Grand Slam Committee Administrator has opened an investigation to determine whether Williams’ behaviour should be considered a “major offence,” which can lead to additional penalties.
Williams also is being docked $500 for racket abuse in what became a 6-4, 7-5 loss on Saturday night.
Williams earned $350,000 in prize money for reaching the singles semifinals. She also is scheduled to play in the women’s doubles final on Monday with her sister Venus.
