ATP Miami - Nadal moves on; Murray gets walkover

World No. 2 Rafael Nadal has reached the last 16 at the Sony Ericsson Open beating 25th seed Radek Stepanek 6-2, 6-2 on Sunday.

“I’m just happy to be in the fourth round, winning two matches with a positive feeling and with comfortable results,” Nadal told reporters after his win. “I’ll just try to keep doing well and try to keep improving my level a little bit.”

Nadal will now meet No. 16 seed Kei Nishikori.

“He’s a fantastic player and it will be a very difficult match for me,” commented Nadal. “He has a big talent to hit the ball very early, to play very aggressive. So he will be a really tough opponent.”

Nishikori scored a 6-4, 6-2 win against Czech Lukas Rosol.

Bulgarian Grigor Dimitrov scored his first top 10 victory over beating No. 7-ranked Tomas Berdych of the Czech Republic 6-3, 2-6, 6-4.

“Today was a great match, a great day for me,” said World No. 101 Dimitrov. “I didn’t expect to play that well. I didn’t make enough first serves, though. [I] got a bit lucky at 4 4 in the third [set], and I was happy to close the match.”

Fourth seed and 2009 champion Andy Murray moved on when Canadian Milos Raonic, the No. 26 seed, withdrew due to a right ankle injury.
