Germany's Tatjana Malek was a surprise first-round winner in the Nurnberger Gastein Ladies in Bad Gastein on Monday as she disposed of fifth seed Carla Suarez Navarro.

The Spaniard had gone into the match confident after reaching the quarter-finals in Prague last week and looked set for a comfortable route to round two after taking the first set 6-2.

But Malek, the world number 77, hit back strongly to score a 2-6 6-2 6-4 victory and ensured Suarez Navarro would be the first seeded casualty of the tournament.

Also on the opening day of action Romania's Ioana Olaru defeated Marta Domachowska 5-7 6-4 6-3 and there was a good win for Germany-based Bosnian Andrea Petkovic over Sandra Kloesel 6-4 6-3.
