SYDNEY - Australia Davis Cup captain Lleyton Hewitt said Monday Nick Kyrgios had a good chance of playing in this week's World Group playoff and backed his young star after a slew of on-court controversies. Australia's number one, who Monday rose to a career-high 15th, in the world, was forced to quit his third round US Open match against Ukraine's Illya Marchenko eight days ago with a hip injury. But Hewitt said the early signs were "very encouraging" that he could feature in the tie against Slovakia beginning in Sydney on Friday. "It was a good hit-out from Nick today. It's going to be management over the next three to four days with him," Hewitt told reporters. Hewitt added that he would probably make a decision late on Wednesday whether Kyrgios would play the tie.
