After ending his losing run to Rafael Nadal, Tomas Berdych was giving nothing away at the Australian Open.
Tomas Berdych was unwilling to give away the secrets to his long-awaited success against Rafael Nadal at the Australian Open on Tuesday.
The Czech ended a 17-match losing run against Nadal with a 6-2 6-0 7-6 (7-5) victory in their quarter-final clash on Rod Laver Arena.
Nadal struggled early and Berdych took advantage, before holding the Spanish third seed at bay in a tough third set.
Berdych said his plans and execution were crucial as he booked his place in the last four at the year's first grand slam.
"I started pretty well. I started with the plan that I set up before the match, and then it turns that it was the right one," he told a news conference.
"I was able to keep going with the same plan all the way through the match.
"Even though the first two sets kind of looked easy, you know, you're playing Rafa and you know what kind of opponent he is and you have to be ready for anything.
"So, you know, that's why I keep myself really focused and was keep going all the way till the end and trying to make my chances.
"Even though he just changed a couple of things - he gets better in the third set - but still I was able to finish it and close it up in three sets."
Berdych has teamed up with a new coach for 2015, hiring Daniel Vallverdu " formerly part of Andy Murray's team.
But the big-hitting 29-year-old Czech was unwilling to go to deep into the changes Vallverdu had made since they teamed up.
"I think I'm going to keep it a bit secret. That's basically what the chemistry of each team is," Berdych said.
"That would be really like, you know, pointless to setting up the tactics and the way how we want to prepare for the matches if I just open up everything here.
"But he changed a lot of things. He changed a lot of positive things. And the best is I'm really able to execute them really, really quickly. That's how it should be."
