Gael Monfils has won his first ATP title in more than two years, surviving a match point and breaking Ivo Karlovic twice in the span of four service games to run out a 5-7 7-6 (8-6) 6-4 winner in the Citi Open final.

The French second seed prevented the 37-year-old Karlovic from becoming the oldest man since 1973 to win ATP singles tournaments in consecutive weeks.

The 13th-seeded Croatian had won all 53 of his service games in the tournament prior to being broken while serving for the championship at 5-4 in the second set.
