Serena Williams scored a straight-sets victory over Victoria Azarenka, 6-4, 6-4 at the 2012 TEB BNP Paribas WTA Championships in Istanbul, Turkey on Thursday. Coming into the match against the world number one-ranked Azarenka, Serena had 15 straight wins against top five players, 10 straight wins against top players and five straight wins against world number one-ranked players.
"I'd been struggling with my serve in my first two rounds—I knew I could do better, so that was keeping me going," Serena said. "And everything was just a little better today. I knew I needed to play better today to win against Victoria, who has had a stellar year. I'll probably have to play her again though - I can feel it."
Serena has now won 46 of her last 48 matches.
Azarenka will next face China's Li Na in the last round robin match of the Red Group, and the winner of that match will qualify for the semifinals in second place in the Red Group, after Serena.
