That tweet was supposed to be a joke nobody implied she had actually said that to Sloane
Here's the whole conversation:
Jane Carruthers @Fine_Life 4h
@TennisReporters Are you watching the Maria v Sloane match? Maria doesn't seem to be in the best of moods tonight...
Matt Cronin @TennisReporters 4h
@Fine_Life Just turned it on. What a bad mood? Did she utter "SHE MADE YOU" to Sloane during changeover
Jane Carruthers @Fine_Life 3h
@TennisReporters Ha! That would be something. She just looks thoroughly fed up..
