Pl. dont equate Saina or for that matter Marina's achievements with those of Sania Mirza' wins in doubles. Its just ridiculous. Doubles is an event, be in badminton or tennis, in which top players hardly participate. Dont glot over Sania Mirza' winning. Moreover, she is partnering top players like Martina Hingis (now) as per partners.
Your heading that SANIA WINS does convey the factual position. Has she single-handedly won the crown? Was her doubles partner just watching from the sidelines? Sania's contribution to the victory is only 50 percent; as her partner is also equally responsible for the win.
