Victoria Azarenka of Belarus thrashed former world number one Maria Sharapova 6-4 6-1 in the final of the WTA tournament in Stanford to win her first title of the year.
The eighth seed, who celebrated her 21st birthday the day before Sunday's final, joked about her age after dispatching the Russian superstar in California.
"I haven't lost a match yet since I turned 21," Azarenka told the official WTA website.
"It's great. I can have cake now".
Azarenka broke the fifth seed three times in a topsy-turvy first set and then breezed through the second as Sharapova made a string of unforced errors.
