Great Britain's Andy Murray will face world number one Rafael Nadal for the first time since 2011 in the quarter-finals of the Italian Open.Murray produced a determined display to beat Austria's Jurgen Melzer before Nadal came from a set down to see off former top 10 player Mikhail Youzhny.On his 27th birthday, Murray faced 10 break points, including five in the ninth game, to win 7-6 (7-1) 6-4.After a slow start, Nadal eased to victory over Youzhny 6-7 (7-4) 6-2 6-1."To be honest it's not a bad thing for me to play Nadal because I haven't played him for a long time," said Murray of Friday's quarter-final."With the French Open and Wimbledon coming I would be quite interested to play him to see how his game changed and all the things I can do to make it difficult for him."Nadal said: "Andy will be a very tough match, he's playing well, but I'm confident I can do it."It is the furthest Murray has gone in the Rome tournament since his semi-final defeat against Novak Djokovic in 2011 and bodes well for the start of the French Open on 26 May.The tournament at Roland Garros is the only Grand Slam in which Murray has not reached the final, but he showed the battling qualities necessary for success in beating world number 67 Melzer for the sixth time in as many matches."This week I wanted to try and play solid tennis as much as possible and I did a pretty good job in tricky conditions," added Murray, who beat Marcel Granollers in round two."There are still some things I would like to do better; it is still a surface that takes me some time to get used to."Murray - US Open champion in 2012 - had never met Melzer on clay and took three of his five break opportunities.Having lost serve in the opening game, Murray found himself exposed to the 32-year-old's forehand as only 56% of his first serves were accurate in the opening set.After saving break in a lengthy ninth game, he closed out the set 7-1 in a tie break - part of a run which saw him win 15 points from 16 to lead 2-0 in set two.Missed break points left Melzer visibly frustrated early in the second and he smashed a racquet at one stage.After breaking to level, he gave away his serve in the set's seventh game, allowing Murray to twice hold serve for the match.Second seed Djokovic beat Philipp Kohlschreiber of Germany 4-6 6-2 6-1 and will next play David Ferrer of Spain after the fifth seed won 6-2 6-3 against Latvia's Ernests Gulbis.World number three Stanislas Wawrinka crashed out in a 5-7 6-2 6-3 defeat by Germany's 36-year-old Tommy Haas, while Bulgarian world number 14 Grigor Dimitrov defeated sixth-ranked Tomas Berdych 6-7 (3-7) 6-2 6-2.China's second seed Li Na went through to the women's quarter-final with a 5-7 6-2 6-2 success over Australia's Sam Stosur, while Serbia's Ana Ivanovic knocked out Maria Sharapova of Russia 6-1 6-4.Serena Williams beat fellow American Varvara Lepchenko 6-1 6-2, while Poland's third seed Agnieszka Radwanska was a 6-4 6-1 winner against Italy's Francesca Schiavone.(BBC)Bakudaily.az
