Call it sneaky, call it ‘SABR’ (Sneak Attack By Roger) or ‘Federer’s Trick-or-treating shot, but this is seen as the new weapon that could just fire Roger Federer to his sixth US Open and 18th Grand Slam title. The world number two has developed a new attacking ploy which is bamboozling opponents and providing the 34-year-old Swiss with yet another dimension to his already impressive game. The video of Federer in attack mode will explain why the tennis fans is going gaga over it. Also Watch: Novak Djokovic does ‘Gangnam Style’ dance at US Open 2015: Watch him celebrate with fan.

It involves chipping and charging on a second serve, starting from a position inside the baseline and ending with a quick sprint to the service box.”We sort of came up with the name, you know, ‘Sneak Attack By Roger,’ ‘Sabre.’ Call it ‘Fed Attack,’ call it whatever you want, but I thought it was kind of funny,” said Federer.

Although he had mixed success with it on Saturday, the world number two still had plenty of other tricks up his sleeve to make the last 16 with a 6-3, 6-4, 6-4 victory over Philipp Kohlschreiber. It was his 10th victory in 10 meetings against the German player as he reached the second week in New York for the 15th successive year. Federer arrived in New York having rebounded from his Wimbledon final defeat to Novak Djokovic with a seventh Cincinnati Masters title.

It was at the Midwest venue where Federer developed his new tactic, almost by accident when he was practicing with French player Benoit Paire. Both men were just looking for a gentle workout with Federer still dazed by jet-lag and Paire laid low with an ear infection. “I was very tired and he was tired, and at the end we said, ‘Well, let’s still play some games just because it feels like it’s the right thing to do,'” explained Federer.

“I was going to stop already, but (coach) Severin (Luthi) said, play a few games get used to the conditions.” “I said, Whatever. Let’s play some games. And, yeah, at the end we were just kidding around almost, and that’s when I said, OK, I’m going to chip and charge and just keep the points short.

“That’s when I started to run in and hit returns. I hit a couple for a winner. They were like ridiculous. He laughed. I laughed. Severin laughed.” Federer said he never imagined using it in match play and that it was Luthi’s persuasion that kept the tactic on the boil. “Severin said, ‘Well, what about using it in a match?’ I was like, ‘Really?’ So he pushed me to keep using it and not shy away from using it on big moments, and not just because you don’t know how you look with a full stadium.

“He was actually the one who pushed me to it. And because we were always talking about that tactic, as well.” “Moving forward it’s an option. Clearly I’m very happy it worked so well in Cincy.” However, he may not get the opportunity to use it in the fourth round, where he will be facing big-serving American John Isner.
