Svetlana Kuznetsova bizarrely cut her ponytail off in the middle of her match against Agnieszka Radwanska at the WTA Finals on Monday.
The two-time grand slam winner became frustrated during the second set and took it out on her hair when she returned to her seat, chopping off part of her ponytail in between games.
Kuznetsova threw loose strands of her hair onto her chair before resuming play and, at the next break in play, proceeded to sob into her towel.
Radwanska went on to secure the second set but the change in hair style clearly helped as the Russian eventually won out in three sets in Singapore. Her actions, which were watched in complete shock by supporters, stole the show on the day.
The world number nine had the following to say on her rather strange antics: "It was bothering me a lot. I was trying to put it behind my headband but my hair is very thick and heavy,"
"Every time when I was hitting good forehands and coming forward, it would hit my eye and I struggled.
"So I thought 'Okay, what's more important now, my hair which I can let grow or the match? Okay, I got to go for it right now' and that's it.
"I was just trying to give myself the best chance and remove what was bothering me. At the time, I don't even know how much I cut there."
The match was an energy sapping and physical affair which the Russian won 7-5 1-6 7-5 which left both players visibly drained but it was Kuznetsova who advanced to the second round.
She said on the nature of the match:
"At some point I was just ready to lie on the court and let them take me out of here. But I kept at it,"
In a week without the antics of Nick Kyrgios, Kuznetsova certainly filled our boots with her one of a kind performance.
