Serbian Viktor Troicki ruthlessly dismantled ailing Kazakh qualifier Mikhail Kukushkin 6-2 6-3 to win the Sydney International for his second career ATP title on Saturday.

The 28-year-old righthander won the last four games of the first set and was 4-1 up in the second when Kukushkin took a medical timeout to have treatment on his left thigh.

The Kazakh rallied to win the next two games for his first break of serve in the match but Troicki was just too strong and broke back before serving out the match and claiming the title with his 13th ace.

Once ranked 12th in the world, Troicki is working his way back up the rankings after a doping ban that took a year out of his career.
