Six-time US Open champion Serena Williams has been embroiled in her share of controversies at Flushing Meadows.
AFP Sport looks at three Williams outbursts in the wake of her clash with umpire Carlos Ramos in a loss to Naomi Osaka in Saturday's final:
2009 - Semi-final against Kim Clijsters
=======================================
Serena argued briefly, went back to the service line then directed a venomous rant at the offending lineswoman including a threat to "shove this ball down your throat."
2011 - final against Samantha Stosur
====================================
"Because you're out of control. You're out of control. Totally out of control. You're a hater and you're just ... unattractive inside. Who would do such a thing? And I never complain. Wow. What a loser. You give a code violation because I expressed who I am? We're in America last I checked."
2018 - final against Naomi Osaka
