If you sometimes confuse Aleksandra Wozniak for Caroline Wozniacki, you are not alone.

Last year, tennis commentator Mary Carillo wrote in an ESPN news release that she was keeping an eye on Aleksandra "Wozniaki" in the upcoming French Open. Carillo obviously meant to write Caroline Wozniacki, but was suffering from a case of the Woz.

Wozniak is used to being mistaken for Wozniacki.

"We're really good friends. We hang out together," Wozniak said. "We both have Polish backgrounds. Her mother played for the Polish national volleyball team. My father played professional soccer in Poland. People get us confused. It doesn't happen that much anymore. I changed the color of my hair. I'm a brunette. I was a blonde for the longest time."

Wozniak, ranked No. 44 in the world and the 12th seed in the Family Circle, cruised to a 6-3, 7-6 victory over American Lilia Osterloh on Monday in a contest that was played in the Family Circle Cup Stadium.

While some tennis followers might have a hard time remembering who is who when it comes to Wozniak and Wozniacki, Wozniak is revered in Canada.

Wozniak was born in Montreal and lives in Blainville, Quebec. The town was renamed "Wozniakville" for a day in August 2008 after she became the first woman from Quebec to win a Sony Ericsson WTA championship event.

"It was really an honor to have the town named after me, even if it was for a day," Wozniak said. "I was the first woman from Quebec to be ranked in the top 50. It was a nice privilege to get the key to the city from the mayor."

Wozniak is making her third appearance in Charleston. She lost in the first round in 2008 and reached the second round in 2009.

Wozniak needed just 30 minutes Monday to win the first set against Osterloh and was up 4-1 and 5-3 in the second set. Osterloh won the next three games but Wozniak was able to avoid a third set.

"I couldn't put her away there for a while," Wozniak said of the 74-minute second set. "She had nothing to lose and started playing relaxed. She started getting her confidence back, but I was able to come back."

Wozniak played in three matches in January and lost in the first round of the Australian Open to, you guessed it, Wozniacki. It was the sixth time in seven matches that Wozniacki defeated Wozniak. Wozniak didn't play in any Sony Ericsson WTA event in February because of a Fed Cup commitment and what would have been a demanding travel schedule including trips to Dubai and Paris.

She began her career by playing on indoor hard courts but now prefers clay, so she will feel at home on Daniel Island.

"It's more physically challenging," she said of clay. "You have to mix it up well. You have to slide and time your shots. This is a big tournament for me. I can improve my ranking if I stick around long enough."

And if she hangs around until the quarterfinals, she could face Wozniacki.

That could give all of Charleston a case of the Woz.
