With back-to-back ATP Masters 1000 tournaments coming up in Montreal and Cincinnati—and the last Grand Slam of the year, the US Open, shortly afterwards—many of the top players are shifting gears from grass courts to hard right now.

But some players, including Dominic Thiem, are going back to clay, which we last saw at Roland Garros.

The world No. 4 is the top seed at this week’s Hamburg European Open, a 500-level clay-court event in Hamburg, Germany. The following week, he’ll play the 250-level Generali Open in Kitzbuhel, Austria.

Thiem has been the second-best player on clay after Rafael Nadal for the last few years, reaching back-to-back semifinals at Roland Garros in 2016 and 2017, and back-to-back finals in 2018 and 2019.

But after another deep run in Paris, Thiem elected not to play any grass-court lead-up tournaments, and he was subsequently ousted from Wimbledon in the first round. He received one of the tougher first-round draws in former No. 11 Sam Querrey, who eventually made the quarterfinals.

No more grass for Thiem

“But it’s a lot of experience, too. I’ll see how I do it next year. I like to play on grass, and of course I’d love to do better at Wimbledon, but playing that deep at the French Open, it’s a tricky situation.”

“Last year and this year together I played four grass-court matches, which is not a lot at all,” Thiem said after that loss to Querrey. “I mean, all the clay-court season, it takes a lot out of me. I gave everything I had physically and also mentally in all of the six weeks until the end of the French Open. Then I had to take the decision to come to Wimbledon without any preparation, and then of course it’s very tough to face Querrey, who loves grass, in my first official grass-court match of the year.
