The world's top two tennis players, Novak Djokovic and Andy Murray, both suffered shock defeats Friday, while Rafael Nadal stormed back to beat longtime rival Roger Federer at the Cincinnati Masters. Number three Nadal booked a spot in the semi-finals by rallying past Federer, with the Swiss player saving four match points in a 5-7, 6-4, 6-3 loss.
The pair have met a total of 31 times, with Nadal winning 21 of those.
"My movement got better, with more intensity," said Nadal, undefeated on hardcourts in 2013. "I put in more balls on the return, and controlled the baseline, something that didn't happen the first set and a half.
"The match was very close. I played some good points in important moments."
Federer suffered only his second loss in the last five editions in Cincinnati. "Credit to him for hanging in and getting back some tough shots," said five-time champion Federer, who will fall to seventh in the world as a result of his defeat.
