OSAKA, Japan (AP) -- Samantha Stosur of Australia swept past American teenager Madison Keys 6-1, 6-2 Saturday to reach the final of the Japan Open.

She will face another teenager on Sunday, after 19-year-old Eugenie Bouchard of Canada beat Japan's Kurumi Nara 6-2, 6-2 to reach her first career WTA tour final.

The third-seeded Stosur was never broken against the 18-year-old Keys and clinched the win in just over an hour.

She said ''you have to make sure you're serving well against Madison so you don't fall behind in a set, because she's got a very, very big serve.''

Bouchard won seven straight games to take a 3-0 lead in the second set and cruised from there.
