Finals Day - or Finals Night - at the Apia International Sydney began with the singles.
Agnieszka Radwanska went into the final with an 8-0 record in 2013 without dropping a set.
Though there were several deuce games, Agnieszka Radwanska kept toughing them out until 60 10.
That's when Dominika Cibulkova admitted it started getting to her during Friday's final.
Dominika Cibulkova would lose 22 of the last 25 points to fall to Agnieszka Radwanska, 60 60.
No WTA final had ended in a double bagel since the Quebec City final in the fall of 2006.
In that Quebec City final in 2006, Marion Bartoli blanked Olga Puchkova by that double bagel.
Agnieszka Radwanska is now 9-0 on the year without losing a set in any of those matches.
Agnieszka Radwanska had never even reached a WTA final on the Australian continent before 2013.
The doubles final followed, with the No.1 team - Sara Errani and Roberta Vinci - in action.
Nadia Petrova and Katarina Srebotnik had other ideas against the Italian pairing, though.
Nadia Petrova and Katarina Srebotnik had already beaten the No.4 and No.2 seeds in Sydney...
And the Russian-Slovenian pairing picked off the No.1 seeds as well, prevailing, 63 64.
Nadia Petrova and Katarina Srebotnik won their second WTA title together, after 2008 Moscow.
Nadia Petrova and Katarina Srebotnik are going to partner up together for the 2013 season.
