First-time Olympian Maria Sharapova advanced to the women's final by beating Russian teammate Maria Kirilenko 6-2, 6-3. Sharapova's opponent Saturday will be Serena Williams or No. 1-seeded Victoria Azarenka.

Kirilenko had a chance to get back in the match when she broke for a 3-2 lead in the second set, but Sharapova quickly regained control with a break in the next game.

That seemed to shatter Kirilenko's spirit. Sharapova went for the kill and let out a scream of joy as she broke for a 5-3 lead.

Sharapova is now guaranteed at least a silver medal following her dominant display against the 14th seed.

"It's incredible, not only to be part of this event and be an Olympian, but to put yourself in with an opportunity to go for gold. It's a really nice feeling," Sharapova said.

"What I have achieved in my career has been amazing. Obviously growing up you have big dreams and you hope to win your certain favourite tournaments.

"I've been really fortunate to win all the Grand Slams and obviously this is my first Olympics so I'm just thrilled to be in the final."

Sharapova has won four Grand Slam titles, including the French Open this year. She missed the Beijing Olympics in 2008 because of a shoulder injury.
