Sania has not been playing her best lately & that's what she'll need to win... Hingis in two, possibly one tough set. She'll frustrate Mirza & make her hit the extra ball which will lead to lots of errors.
Hingis easy. Because Mirza is one of those 'hit it as hard as possible every shot' players. That plays right into Hingis' hands. When she knows you'll swing hard, she can make your shot a low percentage shot with placement.
