Top seed Kristina Mladenovic is out of the Samsung Open after she was forced to retire during her opening match.

The Frenchwoman found herself 7-6 (7-5), 3-2 down against German qualifier Tamara Korpatsch when she threw in the towel due to a back injury.

With the result, world No 176 Korpatsch claimed her first victory over a top 20 player.

“I don’t like to win like this, that she retired. I don’t know if she was already injured at the beginning, or if it happened in the match,” said the German.

She added: “From the beginning, I was a bit nervous, and a bit excited, because I’ve only played one time against such a good player.”

Korpatsch will take on Kathinka von Deichmann, who beat Laura Siegemund as the German also retired while being down 7-6, (7-5), 2-3.

There were a couple of other upsets as fourth seed Anett Kontaveit lost against Vera Lapko while the fifth-ranked Svetlana Kuznetsova was beaten by Mona Barthel.
