Fourth seed Dominic Thiem blew a two-set lead to be dumped out of the French Open in the first round by Spanish veteran Pablo Andujar on Sunday.

The 35-year-old Andujar staged a remarkable comeback to defeat the two-time Roland Garros runner-up 4-6, 5-7, 6-3, 6-4, 6-4 after almost four-and-a-half hours on Court Philippe Chatrier.
