Tomas Berdych, who will play Rafael Nadal in the Indian Wells semifinals, says the reason he has had greater success against Roger Federer than the Spaniard is simply because the match-up works in his favor.

“I think it's quite simple,” Berdych said. “It's the way I play. With my style, I can do a bit more damage to Roger, because I can take the comfort on the court away and he starts to be more under pressure. That's the way when he doesn't feel that optimum and that good on court.”

Nadal owns a 12-3 head-to-head record against the Czech, including 11 straight victories.

“With Rafa, it's way different,” Berdych said. “With his lefty hand and heavy spins, it's very tough, especially in these [slow] conditions. If it's going to be hot like this it could be very, very tough one. But one day I hope that I'm going to find the way how to beat him again, and why not here?”
