<p>World number two Novak Djokovic suddenly ran out of gas as he was knocked out 0-6, 7-6, 6-4 by American Sam Querrey in the second round of the Paris Masters on Wednesday. <br /><br /></p>.<p>Serbia’s Djokovic, who will replace Swiss Roger Federer as the world number one next Monday, breezed through the opening set before losing control. <br /><br />Querrey was trailing 0-2 in the second set but dramatically improved after bagging his first game of the match. <br /><br />Djokovic, who had got into the Halloween spirit by turning up on centre court wearing a Darth Vader mask, ended up being slayed by Querrey’s powerful serve and forehand. <br /><br />“Great tennis at the start but I knew that the main problem today will be the continuity of my energy,” Djokovic, who had a stomach bug last weekend, told a news conference. <br />“Unfortunately, it wasn’t to be after the second set. And during the second set I already felt that physically I'm down and I struggled every game.” <br /><br />A red-faced Querrey was at first just looking to salvage his pride. He ended up pulling off a great escape. <br /><br />“It’s my biggest, this win feels great,” Querrey told a courtside interviewer. “I served great. When I was down 6-0, 2-0 I just wanted to get a game and when I won that game I got a bit more confidence.” <br /><br />The American took an early break in the decider and saved five break points in the ninth game, wrapping an unlikely win on his second match point with a service winner. <br /><br />He will next face Canadian 14th seed Milos Raonic or France’s Jeremy Chardy. Earlier, France’s Richard Gasquet lost his chance to qualify for the World Tour Finals when he slumped to a 7-6, 4-6, 6-1 defeat against the towering Kevin Anderson of South Africa. <br />Serbian Janko Tipsarevic was still on course for one of the two remaining spots in the eight-man season finale after the eighth seed beat Dutchman Igor Sijsling 6-4, 7-6.<br /><br />On Tuesday, Jo-Wilfried Tsonga started his quest for a final spot with a 6-2, 4-6, 7-6 second-round victory over fellow Frenchman Julien Benneteau. Czech Tomas Berdych, the fifth seed who has already secured his London berth, started slowly against Andreas Seppi but eventually sealed a 7-6, 6-2 win. <br /></p>
