Serena Williams defeated defending champion Venus Williams to win the Sony Ericsson Championships – Doha 2009.
Serena beat her older sister Venus for the second time at this year’s Championships and faced no break points en route to a 6-2 7-6(4) victory in the season finale. The match was not spectacular, as most of the meetings of the Williams sisters are. Both players had heavy strapping on their left legs, which was just the appropriate ending to the injury plagued tournament.
Serena, who will end the season ranked No.1, earned $1.55 million in Doha after finishing the tournament undefeated.
