A new world number one emerges this week after Serena Williams finished runner-up at the Qatar Total Open. Victoria Azarenka lost the top ranking despite having successfully defended the title in Doha because Williams was not in this event last year and has added points enough to overtake the Belarussian.

[1] Serena Williams (USA) – 10,590
