Novak Djokovic attends fellow Serbian and childhood friend Ana Ivanovic 's 6-4, 6-2 victory over Kimiko Date-Krumm at Indian Wells.

Djokovic promised to attend one of her matches after she went to both of his semifinal and final wins in Australia. She joked that now they might have to attend all of each other's singles matches.

"If that's what it takes to win, I won't complain," she said with laugh. "It was great to see him there. I actually didn't think he was gonna come. He said, 'I'll come and watch to return the favor from Melbourne.' I was like, 'Sure.' He said, 'Really. Leave me a ticket. Then when he came, I couldn't believe it. Anyway, I think for guys it's much worse watching women's tennis than us watching men's…It was pressure. He won Australian Open and I had to play for him."

Ivanovic spent the week prior to Indian Wells in Las Vegas working out adidas coach Darren Cahill and trainer Gil Reyes. She's not planning on hiring a full time coach any time soon but is consulting with Cahill, who is at Indian Wells. Her hitting partner, France’s Olivier Morel and her personal trainer, Marija Lojanica, are also with her.—Matthew Cronin
