Re: Sania Mirza playing everything again?!?! Jankovic version 2.0
Plenty of players play multiple events at slams. Sania will be fine.
And as people have said, realistically she won't be in the singles much longer anyway. And if by some chance she is, I'm sure she'd do what she needed to do to assure she was ready to give it her all, even if it meant pulling out of one of the doubles.
