Justin Engel: The Breakout Star of the Stuttgart Open
Justin Engel’s performance at the Stuttgart Open was nothing short of extraordinary. Coming into the tournament, the Nuremberg-born prodigy had never played a professional match on grass. Yet, he adapted quickly, displaying a serve and flat backhand that proved lethal against more experienced opponents. Engel’s preparation, guided by former top 20 player Philipp Kohlschreiber, paid off as he claimed his first ATP-level win on grass against James Duckworth and then stunned American Alex Michelsen, a Top 50 player, in straight sets.
Engel’s victory over Michelsen was particularly impressive. He did not concede a single break point and made almost no unforced errors, showcasing maturity beyond his years. This win propelled him into the quarterfinals, making him the youngest quarterfinalist in the history of the Stuttgart Open and the youngest on grass since Boris Becker’s 1985 Wimbledon breakthrough. Engel’s achievement also placed him second only to Rafael Nadal as the youngest player to win matches on all three surfaces—grass, clay, and hard court—since 1990.
Engel’s rise in the rankings was meteoric. His Stuttgart Open run saw him jump 49 spots to No. 232 in the PIF ATP Live Rankings and move up to ninth in the PIF ATP Live Race to Jeddah. The tennis world took notice, and Engel’s name was on everyone’s lips as he prepared for his quarterfinal clash with Felix Auger-Aliassime.
Auger-Aliassime Halts Engel’s Historic Run
Friday’s match was a true test for Engel, as he faced the experienced Canadian Felix Auger-Aliassime, a former US Open semifinalist and two-time Stuttgart Open runner-up. Engel rose to the occasion, putting up a strong fight in the first set and pushing Auger-Aliassime to a tiebreak. Despite his valiant effort, Auger-Aliassime’s experience and power proved decisive. The Canadian took the first set 7-6(3) and controlled the second set to win 6-3, ending Engel’s dream run.
Auger-Aliassime’s victory extends his impressive record at the Stuttgart Open, where he has now reached the semifinals in all three of his appearances. He will next face second-seeded Taylor Fritz, setting up a blockbuster semifinal clash. For Engel, the loss marked the end of a historic week, but it also signaled the arrival of a new star on the ATP Tour. His performance at the Stuttgart Open has inspired fans and fellow players alike, and he is already looking ahead to future tournaments.
