The fifth seed produced a strangely lackluster display as he was outplayed by the world number 52 and suffered his earliest-ever U.S. Open exit.
The left-handed Klizan had never been beyond the second round at a grand slam event before but he surprised Tsonga with some inspired tennis.
Tsonga rallied from 4-1 down in the fourth set to 4-3 but the 23-year-old Klizan held his nerve to seal the biggest victory of his career.
