GSTAAD – Dominic Thiem on Friday reached his first ATP Tour semi-final since May 2021 with a straight-sets victory over Peru’s Juan Pablo Varillas in Gstaad. Thiem missed the second half of last year due to a wrist injury and lost his first six Tour matches this season. “When I travelled to Bastad last week I didn’t expect to reach the quarter-finals there and then the semi-finals here. Then I played two good points and it was 3/5 and I thought ‘Let’s try’,” he said. French Open losing finalist Casper Ruud plays Jaume Munar and Albert Ramos-Vinolas takes on Chile’s Nicolas Jarry in Friday’s other quarter-finals.
