Murray through as Nadal loses.

Andy Murray held off a spirited effort from Stanislas Wawrinka to complete a 6-4 3-6 6-3 win in the last 16 of the Shanghai Masters in China.
But there was only frustration for world number two and top seed Rafael Nadal, who was outgunned by the inspired play of Florian Mayer in an epic match that the German player won 7-6(5) 6-3.
British number one Murray - chasing his third straight title after victories in Thailand and Japan - looked in decent shape against Wawrinka as he advanced to a quarter-final match against Australian qualifier Matthew Ebden, who completed a 6-2 2-6 7-6 (8-6) victory over eighth seed Gilles Simon of France.
Murray was playing his first match in his defence of the Shanghai tournament after Dmitry Tursunov withdrew with a thigh injury before their second-round match on Wednesday.
Murray - who is trying to rise above Roger Federer to number three in the world before the end of the year - made a blistering start to his day in breaking Wawrinka twice in the opening three games on the way to pocketing the first set 6-4.

Wawrinka is traditionally an opponent Murray has problems with having lost to him at the 2010 US Open and suffering four defeats in nine meetings against the powerful Swiss player.
Wawrinka broke Murray in the eighth game of the second set as a loose service game saw Murray drop the second set 6-3, but he recovered to win the opening five games of the third set as Wawrinka visibly began to lose the plot, illustrated by his decision to smash his racquet into pieces in falling two breaks behind at 4-0 down.
He was given a warning before rallying to recover to trail 5-3, but there was only the consolation of avoiding the bagel for Wawrinka as Murray - unbeaten since losing to Rafa Nadal in their US Open semi-final - served out the match by winning the second of two match points to progress.
"I got myself pumped up right at the beginning of the third set," said Murray. "Stan was playing very well. I was trying to control the ball.
"I was really struggling in middle of the second set. I really had to make sure I got my feet moving."
Mayer will face Feliciano Lopez of Spain, who upset the sixth seed Tomas Berdych of Czech Republic 6-4 6-4. Lopez unearthed a serving master class, aided by the indoor conditions with the stadium roof closed due to rain. Lopez broke Berdych in the ninth game of the first set and the opening game of the second set before seeing out the win with some ease. He did not face a break point in two sets.
Both Nadal and Mayer produced an immaculate opening set of tennis on serve, but Mayer edged the tie-break 7-5. Nadal narrowly missed an attempted forehand winner at 5-5 before an ace helped Mayer take out the set much to the delight of an excited crowd.
Mayer was under severe pressure in the early moments of the second set but stuck manfully to his task in twice saving break points before himself breaking Nadal in the seventh game of the set.
With Nadal clearly feeling the frustration against Mayer's superior play, Nadal dropped his final service game as Mayer - ranked 23rd in the world - bounded towards the net from a volley before seeing a passing shot drop just inside the baseline to complete a famous win.
In their first match on tour, Mayer must be one of the few men to hold a winning record against Nadal.
It is easily his finest win as he hit 29 winners while converting 21 out of 29 approaches to the net.
David Ferrer hit back from three match points down to beat fellow Spaniard Juan Carlos Ferrero 1-6 7-5 6-2.
Ferrer's victory over Ferrero coupled with Andy Roddick's 6-3 6-4 victory over Nicolas Almagro earlier in the day ensure third seed Ferrer of a place at November's World Tour Finals at the O2 Arena in London, a tournament reserved for the world's top eight players.
Ferrer will face Roddick in the Shanghai quarter-finals on Friday.
Ukrainian Alexander Dolgopolov will face Kei Nishikori of Japan in the last eight.
Dolgopolov recovered from losing the first set to Bernard Tomic in completing a 5-7 6-1 6-0 victory, while Nishikori followed up his shock win over Jo-Wilfried Tsonga in the previous round with 7-6 (8-6) 4-6 6-3 win against Santiago Giraldo.
