Nick's Picks For Day 7

Legendary tennis coach Nick Bollettieri offers his commentary and prediction for three of the hottest matches on Sunday’s schedule.

[15] Ana Ivanovic vs. [20] Daniela Hantuchova
Daniela has been in a lot of wars, but she's in great shape, her groundstrokes are impeccable, and she's still fast. She has to keep Ana in the back of the court with deep balls, move her around, and make her over hit. And Daniela needs to come to the net, which she can do. She's an excellent doubles player and she's never been afraid to volley or play defence. But Ivanovic seems to be regaining her confidence. I would give a little edge to Ivanovic-she's more aggressive than Daniela and she's on a roll, after a hell of a week in Indian Wells. Ana will have to hit a lot of extra balls in this one, but she should get the win.

NICK'S PICK: Ivanovic in 3 sets

[4] Andy Murray vs. [26] Milos Raonic
This Canadian boy, Raonic, is striking the ball very hard and he's picking up a ton of confidence. He's won two titles already this year. But this match will be won or lost by Andy Murray. The surface here fits him very well. It's not overly fast, the balls bounce fairly high, and the fact that this is going to be a day match favours Murray. Even though he had a slip in Indian Wells last week, you can tell that Ivan Lendl has been a major influence on Andy. He's driving his forehand and playing more aggressive. And, above all, he's moved his position closer to the baseline and that's a big plus for his game, so I give the edge to Murray.

NICK'S PICK: Murray in 2 sets

[2] Rafael Nadal vs. [22] Radek Stepanek
Stepanek played extremely well against Tommy Haas in his first match. They live next door to each other near my Academy in Bradenton, so I called it the battle of the neighbours. Stepanek has the all-around game. He hits the ball flat and very early, serves and returns well. However he cannot beat a player like Nadal from the baseline. In order to even have a chance against Nadal, Stepanek has to come inside the baseline sometimes and force the issue. But let's face it, Nadal is angry. He's swinging hard at the ball, he's whipping the backhand over his shoulder. And he's tired of being in the finals here but not winning one. You can bet on him to get through.

NICK'S PICK: Nadal in 2 sets
