What would you do to win a tennis match? Would you give it all you had? Youre probably nodding your head emphatically and saying, OF COURSE from your desk right now.But what are you really?willing to sacrifice to get the victory? If youre not quite sure what Im asking here, please allow me to share what Svetlana Kuznetsova did during her group-stage match on Monday against Agnieszka Radwanska at the WTA Finals.After winning the first set, Kuznetsova began to struggle in the second, so she took drastic actions during the changeover. Instead of merely mentally regrouping and drinking water, the No. 9-ranked player CUT PART OF HER PONYTAIL OFF.Thats right, world. SHE CHOPPED HER HAIR OFF FROM HER SEAT ON THE COURT WITHOUT A MIRROR.And if you dont believe me, there is thankfully video footage of the shocking moment below. Please watch for yourself.Now THAT is a whole other level of dedication to your craft. And thankfully, the move seemed to have worked. After losing in the second set and trailing in the third, Kuznetsova ultimately rallied and won, 7-5, 1-6, 7-5.See something entertaining on social media that you think deserves to be shared?
