PARIS (AP) Unseeded Mona Barthel of Germany won her second career title Sunday, upsetting top-seeded Sara Errani of Italy 7-5, 7-6 (4) in the Open GDF Suez final.
The seventh-ranked Errani was a heavy favorite as she chased her seventh career title and first this year, but the 45th-ranked Barthel stayed on a roll after beating fifth-seeded Roberta Vinci and No. 3-seeded Marion Bartoli on her way to the final.
Barthel played aggressively, with 53 winners and 50 unforced errors. She clinched the victory with a forehand winner. Her previous title came in Hobart, Australia, in January 2012, when she came through the qualifiers.
