Serena Williams' US Open final outburst will cost her.

Williams was fined a total of $17,000 for three code violations during her 6-2, 6-4, loss to 20-year-old Naomi Osaka in the US Open final.

The tournament referee Brian Earley fined Williams $10,000 for verbal abuse of chair umpire Carlos Ramos after the 23-time Grand Slam champion called the veteran chair umpire "a thief."

The 17th-seeded Williams was fined $4,000 for being warned for coaching, and $3,000 for smashing her racquet.

The $17,000 fine will be deducted from the $1.85 million Williams earned as US Open runner-up.
