Learner Tien of the United States is set to start his grass-court season against Yoshihito Nishioka of Japan in the first round of the 2025 Boss Stuttgart Open.
Tien, who has lost his last three matches on clay, will now begin his grass-court campaign in Stuttgart. The 19-year-old American had struggled adapting to the playing conditions on clay, winning only 3 of 10 matches on the red dirt this year. Nevertheless, it was a learning experience for a still-improving Tien, who is now preparing for his first ATP main tour campaign on grass.
As for Nishioka, he enters the Boss Open aiming to end a five-match win drought that saw him go winless during the clay-court season and drop his first grass-court match this year. The Japanese lost his first-round matches 2025 Italian Open and the French Open before falling to Adrian Mannarino of France 7-6(1) 3-2 ret.at the 2025 Birmingham Challenger.

Our Learner Tien vs Yoshihito Nishioka Prediction
Why you should bet on Yoshihito Nishioka +1.5 Sets (Win $100 on a $140 Bet): This is a dangerous match for Tien, who has yet to play a grass-court match since turning professional. On the other hand, Nishioka is a career 13-17 on grass and went 5-2 in 2024. While I still believe that Tien is the more skilled player of the two, Nishioka’s experience on the fast grass-court surface could present a challenge for the still inexperienced American teen. I would have picked Nishioka to win straight-up over Tien, but I had a second thought about going all in because of his 5-match losing streak, which is a confidence-killer for any player.
