It was the 21-year-old's third victory in a month and follows her maiden triumph on the WTA tour at the Nuremburg Open in June before winning at 's-Hertogenbosch, one week later.
Meusberger, who came into the tournament ranked 112 in the world, will see her stock rise after levelling the match at one set all with a 9-7 tie break win in the second set before running out of steam in the decider.
