NEW YORK - A new member of the coaching squad for world number one Novak Djokovic, former top-10 player Wojtek Fibak, is quickly paying dividends for the six-time Grand Slam champion from Serbia. Djokovic cruised into the second round of the US Open on Tuesday, defeating Ricardas Berankis 6-1, 6-2, 6-2. "We worked very well last six, seven days of the preparations for the Open and tonight's match went really well," Djokovic said of Fibak. "He has an important role in the team. He's consulting myself." Djokovic, the 2011 US Open champion who lost to Britain's Andy Murray in last year's final, also fell to Murray in last month's Wimbledon final and then he lost to Rafael Nadal in a Montreal semi-final and John Isner in a Cincinnati quarter-final. –AFP
