Justin Engel Reaches Stuttgart Quarterfinals at 17

Seventeen-year-old German Justin Engel became the youngest player in 40 years to reach a men's tour grass-court quarterfinal at the 2025 Stuttgart Open, with victories over James Duckworth and seventh seed Alex Michelsen. Engel, playing his first professional grass-court matches, overcame dizziness and a deficit to defeat Duckworth, then beat Michelsen without facing a break point. His impressive run ended in the quarterfinals with a loss to Felix Auger-Aliassime, who advanced to face second seed Taylor Fritz in the semifinals. Top seed Alexander Zverev also reached the semifinals and will play Ben Shelton, who is set to enter the ATP Top 10 for the first time. The Stuttgart Open acts as a significant lead-in to Wimbledon, highlighting young talent like Engel. Fritz, Shelton, Auger-Aliassime, and Zverev make up a competitive semifinal lineup.
