Pablo Andujar is celebrating a massive upset…

The 35-year-old Spanish tennis player defeated reigning US Open champion and two-time French Open finalist Dominic Thiem 4-6, 5-7, 6-3, 6-4, 6-4 in the first round.

Andujar, ranked 68th in the workd, came back from two sets down to claim the Roland Garros win against the fourth-seeded Austrian.

It marked the first time in eight appearances at the clay-court Grand Slam that Thiem lost his opening match.

Andujar also defeated Roger Federer in Geneva earlier this month. It’s the first time in his career that Andujar has come back to win after losing the opening two sets.

Thiem, who lost the 2018 and 2019 finals to Rafael Nadal, dropped to 11-9 in five-set matches.
