'What's more important?' - Kuznetsova explains mid-match haircut

Updated: 

Svetlana Kuznetsova put WTA Finals glory ahead of her vanity on Monday, slicing off her ponytail mid-match on her way to a thrilling victory over reigning champion Agnieszka Radwanska.

Kuznetsova, playing her second big match in three days after a Kremlin Cup final win over Daria Gavrilova that booked a last-minute ticket to Singapore, beat Radwanska 7-5 1-6 7-5 in a sapping White Group contest that lasted almost three hours.

As Radwanska fought back in the second set, Kuznetsova stunned onlookers as she took to her hair with scissors, later explaining that a heavy ponytail was putting her off ground strokes.

"It was bothering me a lot. I was trying to put it behind my headband, but my hair is very thick and heavy," Kuznetsova explained. 

"When I was hitting the forehands every time I would hit a good shot ... it would hit my eye every time and I had struggle.

"I thought, 'OK, what's more important now? My hair, which I can let grow, or the match?'... I thought, 'OK, I've got to go for it right now', and that's it."

It remains to be seen whether Kuznetsova will enlist the services of a professional to finish the job she started, with a day to recuperate before taking on Karolina Pliskova, another three-set winner in Singapore on Monday.
