John Isner and Reilly Opelka follow the same player pattern. Both Americans, standing over two meters tall, have relied heavily on their serve, although Isner introduced certain variations in his tennis throughout his career. Opelka, for now, continues to play his cards with his serve.
And, coincidentally, both have been coached by the same coach, Craig Boynton. The Ohio native made a name for himself during his time with Jim Courier, then went on to guide many other American players like Mardy Fish or Jack Sock, but he spent a total of three years with John Isner. Moreover, before embarking on his adventure with Reilly Opelka, he worked with Hubert Hurkacz, showing his preference for being surrounded by big servers.
However, when comparing Isner to Opelka, Boynton finds differences. So far, Isner's career has been more successful, with a Miami Masters 1000 title among the 16 that he has won, reaching a career-high ranking of number eight in the world. In contrast, Opelka currently holds four ATP titles, with his highest ranking being the 17th position in 2022.

Craig Boynton sees less resemblance between John Isner and Reilly Opelka
Beyond each one's achievements, Boynton, who knows them both, confirms their differences: "They are two different people. Ultimately, all the players here have the same goal, but each one has different skills. Obviously, people will notice the similarities between Reilly and John, but they are different players," stated the coach in comments collected by ATP.
He emphasizes that although both are power servers, their approach differs: "They have some similarities, but they are different in almost every aspect. Simply put, they are different individuals, different players, who ultimately try to achieve the same thing but do it differently."
While Opelka praised his new coach: "He is one of the best coaches in the world, and I believe that between him and Jay Berger, I am extremely lucky. They are great people, intelligent, tennis geniuses, tennis experts."
The year 2026 presents a key moment for the giant from Michigan. After two years of consistent comebacks following his hip surgery that left him without an ATP ranking, the American returned to the elite in 2025 and made a rise of 234 positions. A year ago, he was ranked 293rd, and by the last week of December, he had reached the 50th spot. However, this season he will have to fight to stay in the top rank, one of the most challenging tasks currently due to the parity prevailing on the circuit.
So far, he has not met these expectations as he lost in the round of 16, descending by thirteen places, while defending his final in Brisbane. Furthermore, his narrow defeat in three tie-breaks against Kamil Majchrzak, where he had three match points, has deeply affected him: "It's a very tough loss that could last a long time, maybe ten years."
It remains to be seen what this new year holds for Reilly Opelka, a player compared to another big server like John Isner. Only time will tell if his career proves to be better or worse than the giant from Greensboro.
