Top-seeded Gilles Simon rallied to overcome Polish qualifier Lukasz Kubot 3-6 6-1 6-3 on Friday and reach the semi-finals of the Nastase Tiriac Trophy.

The Frenchman converted six of his 15 break points to secure the victory in 2 hours, 13 minutes.

Simon said “Kubot played a very good match at the beginning; he was very aggressive,” adding that “I was a little bit tired, not moving perfectly … but finally I was able to break him.”

Qualifier Fabio Fognini upset fellow Italian and six-seeded Andreas Seppi 6-4, 6-7 (4), 6-4, while Germany’s Matthias Bachinger defeated countryman Daniel Brands 6-4, 6-1.
