A beaming Mirza was delighted to be back on court after the painful wrist problem which forced her out of the Beijing Olympics in tears and left her unable even to lift a fork to eat.
Mirza is taking part in the World Team Challenge exhibition event here following treatment recommended by Singh, her friend and an Indian Test batsman.
"Coming back from a career-threatening injury makes it very special to be back," said Mirza.
"Suddenly, from a professional athlete, you become someone who can't pick up a fork," she said.
"I'm just living in the moment and I'm just happy to be back."
The 22-year-old, who reached a career-high ranking of 27 in August 2007, plummeted down the rankings last year as injury blighted her season and is now ranked 100.
