Nadal through to Miami semis
Rafael Nadal came through a gruelling encounter with Tomas Berdych to set up a semi-final with Roger Federer at the Sony Ericsson Open.
The Spaniard set up yet another encounter with his rival Federer by coming through a rematch of last year's Wimbeldon final 6-2 3-6 6-3 at the ATP tour event in Miami.
Nadal was on top from the off, dominating the first set before his Czech opponent found his rhythm to take the match into a decider.
The momentum looked to be swinging back in Berdych's favour when Nadal required courtside treatment for a shoulder and neck problem, only for the 24-year-old to dig deep and take the third set.
After the game Nadal said he wasn't concerned the injuries which affected him against Berdych would trouble him when he took on Federer in the semi-finals.
"When it happens for the first time, it's something where if you don't know what's going on you lose concentration (and start) thinking about the arm," he said.
"If it happens tomorrow (Saturday) it's not going to be nothing new and it will be easier to manage the situation. So I am sure that the arm is not going to affect the match."
In contrast to Nadal's tough day Federer had a very comfortable passage through to the last four after his opponent Gilles Simon had to retire during the first set of their quarter-final.
