ISTANBUL, Turkey - Serena Williams maintained her perfect record against Agnieszka Radwanska at the TEB BNP Paribas WTA Championships - Istanbul on Wednesday, wrapping up Day 2 of the WTA finale with a straight set win over the popular Pole, 62 64 - her eighth win in their eighth career meeting.

Watch highlights, interviews and much more video from Istanbul all week, right here!

Williams has always matched up well against Radwanska - in their seven previous meetings she had only lost one set, and she was winning that set too - and she continued that pattern this time, storming out to a 62 31 lead and, after Radwanska caught up to 62 44, winning two quick games to close it out.

"It wasn't easy - it's the end of the year and I'm a little tired, so I really had to fight in that second set to stay up mentally," Williams said afterwards. "But I just tried to recover and I'm happy I could win."

The No.1-seeded Williams was a study in aggression throughout the match, firing 35 winners to just 24 unforced errors and winning 18 of 22 points at net. She also converted four of five break points.

It was also a fairly good day for Radwanska - she also had a positive differential, nine winners to six unforced errors - but the No.4-seeded Pole only converted one of eight break points in the match.

At the end of the day, Williams improved to 8-0 lifetime against Radwanska, her most wins without a single loss against any player in the Top 17 (she is also 8-0 against No.18-ranked Maria Kirilenko).

And so Williams will go from one perfect record to another now - on Thursday she will play No.5 seed Petra Kvitova in her final round robin match. Williams has beaten Kvitova in all four of their previous meetings, but while the first three were in straight sets, the last one was anything but simple.

The last time Williams and Kvitova clashed it was the quarterfinals of the Qatar Total Open in Doha this past February, and not only was there history on the line - Williams would regain the World No.1 ranking if she won that match - but Kvitova was on fire, storming out to a 4-1 lead in the third set.

Williams overcame it all, though - watch the match highlights and watch Williams' emotional on-court interview afterwards. And, of course, watch the classy pair's big rematch in Istanbul tomorrow.
