No problem with Sania's game: Vijay Amritraj

New Delhi, Oct. 11 (PTI): The inconsistent Sania Mirza today got a pat on the back from former tennis ace Vijay Amritraj, who said there was nothing missing from the teenager's game and her progress should not be judged on a weekly basis.

"I see nothing wrong with Sania's game. She had done remarkably well over the last two-three years," the former Davis Cup captain said here.

However, Amritraj said that the Hyderabadi needed to improve her consistency at the highest level of the game.

Sania has had some good results in the last few weeks, but her wins over higher ranked opponents, notably former world number one Martina Hingis in Korea, have been usually followed by reversals against players ranked below her.

"Everyone strives to be more and more consistent but very few manage that," Amritraj, who reached a career-high ranking of 13, said.

"One should judge her over a whole season. As a rule, if she has five or six good weeks in a season, she can maintain her ranking."

But he pointed out that it was more important to do well in bigger events such as the Grand Slams, Masters Series and Tier I events, as they carried more ranking points.

He mentioned that world number one Roger Federer was an exceptional case.

"Federer is just playing on a different planet because he never lets his physical capabilities drop.

"No one questions other top players like Rafael Nadal or Andy Roddick if their performances fluctuate, because they know that it is very tough. But Federer is head and shoulders above everyone else," Amritraj said
