Victoria Azarenka remains questionable to compete at the Sony Open in Miami, as the right ankle injury that forced her to pull out of her quarterfinal against Caroline Wozniacki in Indian Wells last week continues to hamper her.

"Well, I'm here and that's already a good sign," she told reporters. "The improvement every day is going better and better. It's too early for me to say right now, but I'm glad that it's improving. That's the important thing. I still have a couple of days to get better. I'm in a positive mood…It's not pleasant, but I have to think positively in this particular time. It's not life-threatening; it's just an unknown situation."
