Top-seeded Li Na of China secured a hard-fought 6-3, 1-6, 7-5 victory over Klara Zakopalova of the Czech Republic on Saturday to capture the inaugural Shenzhen Open.

The 2011 French Open champion won her seventh WTA title despite serving 10 double-faults compared to none from her fifth-seeded opponent.

Li rallied after dropping serve in the opening game of the deciding set, winning five of the next six games to build a 5-2 lead.
