Chanda wins her second round match at the U.S. Open, 7-5, 6-3 over Antonella Serra Zanetti. The fact she finished strong would seem to speak well about the condition of her knees.
I might be even more optimistic if she wasn’t facing Venus Williams in the third round. (Then again, Venus had to go to a tiebreaker in the first set against intriguingly named nobody Shikha Uberoi.)
