Third seed Jelena Jankovic cruised into the DFS Classic final on Saturday, taking less than an hour to beat American Laura Granville 6-2, 6-2.

The 20-year-old from Serbia and Montenegro, who is yet to drop a set at the Wimbledon warm-up event, had too much firepower for the unseeded Granville, clinching victory in 53 minutes.

"I didn't expect to reach the final here," said the world number 20. "I've only played a handful of matches on grass, so this is a surprise."

She will play defending champion and top seed Maria Sharapova or Tatiana Golovin of France in Sunday's final.
