Andy Murray crushes Tomas Berdych at Shanghai Masters

He will next meet No. 16 seed Jo-Wilfried Tsonga, who in his quarterfinal outlasted No. 12 Kevin Anderson 7-6(6), 5-7, 6-4.

There was no such drama for Djokovic as the world number one dropped only three games against Klizan.

In the post-match press conference, Nadal, who reached the final of last week’s hard-court event in Beijing, losing 6-2, 6-2 to Serbian world No. 1 Novak Djokovic, said he was pleased with his better recent results. After that victory, the rest of his season was derailed by a wrist injury and appendicitis, and when he returned this year, he’s had to overcome doubts he’d be able to return to his old form.

Djokovic did not see himself as a clear favourite but added: “I’ll try to use the confidence and the kind of comfortable optimistic approach that I had to all the matches in these last couple of weeks”. “Is obvious that I consider myself one of the best players in the world after the career that I having”.

Nadal rolled past fourth-seeded Swiss Stan Wawrinka 6-2, 6-1.

The French Open champion, who won last week in Tokyo, made 34 unforced errors and was on target with just 45 percent of his first serves as he folded meekly. “It’s that simple. Against Nadal you can not do anything if you’re not 100 percent”, Wawrinka said. “Against Nadal you can not do anything if you’re not 100 percent”. He spent more time practicing before the match (80 minutes) than he did on Stadium Court (63 minutes).

Murray lost the first set on a tiebreak and he snapped at the umpire as his frustrations rose in the second set, before he finally broke the big-serving Isner and levelled the match at a set each.

Spaniard through to the third round after a three-set win, while Djokovic progresses comfortably. “Obviously was a huge relief for me to win the first set”. Djokovic, however, leads their head-to-head record by 19 wins to nine.

An off-colour Berdych struggled with his serve throughout the match, landing only 54% of his first serves while winning just 18 points whenever he was successful with one.

“Today, I felt that I was not playing with as much nerves when I am on court”, Nadal told the ATP website (www.atpworldtour.com). I was playing a few good tennis and hanging with him.

“We played the 2012 final here which was an incredibly close match”.

Murray took the next to deuce, sitting on break point twice before a great backhand from Isner helped keep the American on track as he went 2-1 up, while the next three games also went with serve.
