Australia's Bernard Tomic has admitted that there was not much that he could do as he fell to a defeat to Tomas Berdych in the last 16 of the Australian Open.

Tomic's Czech opponent proved to good in Melbourne, recording a 6-2 7-6 6-2 victory at the Margaret Court Arena to move into the quarter-final stage.

"When he's playing good, you cannot do anything," Tomic told reporters after the loss. "You just have to stick in the match and hopefully turn it around. Today he was just playing well and he was going for his shots. There was not a lot I could do.

"If I would have played better, served better, I might have had a better chance maybe after that second set. Who knows.

"But, look, he's been there four, five, six years in the top seven, eight. He's an amazing player."

Berdych will now face third seed and 2009 champion Rafael Nadal in the quarters on Tuesday.
