Venus Williams beat Alize Cornet in straight sets to win the Dubai Championships title for a third time.
The 33-year-old American, now down at 44 in the world rankings, gained revenge for her sister and world number one Serena, who suffered a semi-final defeat by the Frenchwoman on Friday.
Venus used all of her experience to record a 6-3 6-0 victory against the world number 26 in Saturday's final.
Dubai is a happy hunting ground for the seven-times Grand Slam champion - this win follows those in 2009 and 2010.
Cornet's impressive victory over Serena in the last four means the Williams sisters have still not met in a final since 2009.
Venus was not in a mood to join her sister in defeat, however, and beat the 24-year-old Frenchwoman in a match lasting 91 minutes.
Key to the victory was the fact she converted five of eight break points against the Cornet serve, while her French opponent only took advantage of one out of six such opportunities to come her way.
