British number three Naomi Broady fought back from a set down to beat Karin Knapp and reach the second round of the Katowice Open in Poland.
The 26-year-old - ranked 78 in the world, six places lower than Italian Knapp - won 6-7 (6-8) 6-4 6-4.
Although the big-serving Broady wasted a set point in the first-set tie-break, she broke early in the second.
Next she faces defending champion Anna Karolina Schmiedlova of Slovakia or France's Pauline Parmentier.
