Novak Djokovic rallied from a set down to capture his second title of the year, beating Jurgen Melzer 4-6 6-3 6-2 in the final of the Open de Moselle tournament.

The third-seeded Serbian fired 10 aces and converted four of 11 break chances to follow up his first ATP title at Amersfoort in July.

The 19-year-old has won 18 of his last 22 matches, a run that includes a runner-up showing at Umag, Croatia.

Included in that stretch was a win over local favourite Sebastien Grosjean in Saturday's semi-finals.

Djokovic bounced back from the loss of a first-set tiebreaker for a 6-7 (4-7) 7-6 (7-1) 6-3 victory.

Djokovic earned US$55,000 for the win.

This year, he has claimed 34 wins on the circuit, second only to Britain's Andy Murray (37) for most by a teenager.

Melzer had won his previous nine matches but dropped to 1-4 in career finals. The 25-year-old was playing in his first tournament since winning at Bucharest in mid-September.
