STANFORD, Calif. — Venus Williams has been upset by France's Marion Bartoli 6-2, 5-7, 6-4 in the championship match of the Bank of the West Classic.

Williams, making her first appearance at the event since 2005, reached her seventh final in eight appearances at Stanford. She's won two titles but none since 2002.

The eighth-seeded Bartoli, who lost in last year's final, played a steady match Sunday against the second-seeded Williams.

The win will likely move Bartoli up two places to 12th when the next rankings are released.
