"I get asked that all the time, but I feel like I'm just in the moment right now," Williams said. "For this moment, I'm playing well."Williams has 15 Grand Slam titles to her name, including five Australian Opens, a record second only to Margaret Court's 11 Australian titles. Given Williams' recent form in the majors, the quest for a calendar year Grand Slam is very much in play in 2013.

　　"That's an incredible goal. It hasn't been done since the '80s," said Williams. "I don't know if I can do it. Maybe someone else can. We'll see."As the reigning Wimbledon and US Open champion, achieving that feat would means winning six Grand Slam titles in a row.

　　Williams comes into Australian Open 2013 with the Brisbane title already under her belt, but doesn't see herself as a clear favorite in Melbourne.

　　"I don't think like that," she said. "I feel like I have to win seven matches. Everyone in this draw has to win seven matches. They have the same opportunity to do it as I do."
