Dominic Thiem on Friday reached his first ATP Tour semi-finals since May 2021 with a straight-sets victory over Peru’s Juan Pablo Varillas in Gstaad. The former US Open champion won 6-4, 6-3 and will next face either second seed Matteo Berrettini or Pedro Martinez as he looks to make a first final since the 2020 ATP Finals.

Thiem missed the second half of last year due to a wrist injury and lost his first six Tour matches this season. “I failed to serve out at [5-2 in the first set], but it was also the nerves a little bit because it is my first semi-final in one and a half years,” said Thiem, who also reached the quarter-finals in Bastad last week.
