Serena Williams has been fined $10,000 by the U.S. Open for verbally abusing and threatening a lineswoman in her semifinal match against Kim Clijsters. That is the maximum fine allowed for penalizing unsportswomanlike behavior. Williams must also pay $500 for breaking her racquet.
The committee investigating the incident will determine whether it can be considered a "major offense." Such a finding would lead to additional penalties for Williams.
