Maria Sharapova said she would “play in the parking lot” if required after winning her third match on Arthur Ashe Stadium at the US Open.
The Russian, 30, beat 18-year-old American Sofia Kenin 7-5 6-2 in the third round in New York.
Fifth seed Caroline Wozniacki had been critical of the decision to put Sharapova on the stadium court as she needed a wildcard after a doping ban.
“I don’t make the schedule,” said Sharapova, the 2006 champion.
“I’m a pretty big competitor. If you put me out in the parking lot of Queens in New York City, I’m happy to play there.
“That’s not what matters to me. All that matters to me is I’m in the fourth round. Yeah, I’m not sure where she is…”
Former world number one Wozniacki was beaten in the second round on Wednesday, having been scheduled on court five and later moved to court 17.
