Tsonga seals sixth title with Metz win over Ljubicic
Ljubicic, who had not dropped serve on his way to the final, trailed 4-5 in the second set but held serve to force a tiebreak that he won 7-4.
The effort cost the Croat dearly and he gradually ran out of steam against the 2008 Australian Open runner-up.
Tsonga, whose career has been hampered by injuries, sealed the win when Ljubicic served a double fault.
