Martina Hingis might be at the top of women’s doubles tennis, but her ability to grind out wins in the singles could be a matter of concern for Hyderabad. The former no.1, Hingis has retired from the format, owing to which the Swiss might be under-cooked for her singles encounter in CTL. Moreover, the physical demands of singles could also be a daunting task for Hingis to handle. That said, her match against the upcoming Heather Watson of Chennai could be an interesting one. The Brit might have a heavy game, but her tendency to shank shots off both flanks could open the door for Hingis. Watson might still end up over-powering her older pro, but if the veteran can hang in there, a window of opportunity could arise.
