Watch: Stan Wawrinka Reduced To Tears After Squandering Opportunity To Win First Title in 6 Years

An incredible drama unfolded in the Umang clay-court event as Australia's Alexei Popyrin fought back from a set down and overcame cramping as he shattered Stan Wawrinka's hopes of a first title in six years on Sunday.

"The physio said, 'If you go any more then it will be tough'. I said, 'There's no point in quitting now, I'm here in the final. If I lose, I lose. If I retire, I lose anyway. So I have a better chance of winning if I stay in', so that's what I
