Bosnian qualifier Mirza Basic won the Sofia Open to claim his first ATP Tour title following a thrilling victory against Marius Copil on Sunday.
Basic, who sensationally knocked out top seed Stan Wawrinka in the last four, overcame a determined Copli to win 7-6 (8/6) 6-7 (7/4) 6-4 in two hours and 21 minutes.

Pouille, who saved two match points in his semi-final against Jo-Wilfried Tsonga on Saturday, needed just 87 minutes to despatch of Gasquet in the all-French encounter.
The 23-year-old sealed a commanding 7-6 (7/2) 6-4 victory to claim his fifth tour title.
