U.S. Open tennis: Carolina Wozniacki miffed at Maria Sharapova's billing

Caroline Wozniacki didn't go quietly after being bounced from the U.S. Open.

The fifth-seeded Dane took issue with the tournament for having her play somewhere other than Arthur Ashe Stadium while unranked Maria Sharapova was able to compete on that court Wednesday.

"I think putting out a schedule where the No. 5 in the world is playing on Court 5, fifth match on after 11 (p.m. ET) -- I think that's unacceptable, you know," the 27-year-old Wozniacki told reporters.

"And when you look on Center Court -- I understand completely the business side of things and everything -- but someone who comes back from a drug sentence -- performance enhancing drugs -- and then all of a sudden gets to play every single match on Center Court, I think that's a questionable thing to do."

Sharapova is competing in her first major since her 15-month doping suspension ended in April. The Russian followed up her first-round upset of second-seeded Simona Halep with a 6-7 (4), 6-4, 5-1 victory over Hungarian Timea Babos on Wednesday.

A former No. 1 player in the world, Wozniacki reached the U.S. Open final in 2009 and 2014. She will not be advancing that far this season after dropping a 6-2, 6-7 (5), 6-1 decision in her second-round match to unranked Russian Ekaterina Makarova on Wednesday.

"I think it doesn't set a good example, and I think someone who has fought their way back from injury and is 5 in the world deserves to play on a bigger court than Court No. 5," Wozniacki said. "Finally they moved us to Court 17, which is a really nice court actually, and we had a great atmosphere out there. But I think they should probably look into what they need to do in the future."
