John Isner has reached a career-high of number eight on the ATP Rankings and in times where the Big Three have been extremely dominating in the tennis world, he has kept the American flag flying high. Below, we try to dissect which tennis racquet Isner uses and what are the specifications associated with it.

Isner is one of the best servers in the sport of tennis and often leads the annual aces charts. He is also famous for featuring in what is the longest match in the history of tennis, spread across three days at the 2010 Wimbledon against Nicholas Mahut.

The American won that match in five sets, with the final set lasting 138 games in total.

Interestingly Isner was also involved in another rather long encounter, again at Wimbledon in 2018. This was Isner’s only Grand Slam semifinal to day where he faced Kevin Anderson, another tall-serving player and lost 7–6, 6–7, 6–7, 6–4, 26–24.

As mentioned earlier, Isner’s biggest strength is his serve. Apart from being quite powerful, Isner scores over his opponents because of the consistency of his serves, with his tall frame of 6’10.5″ aiding him in this endeavour no end.

Isner’s game is based around his serve and while he does get to the net at times, he is not a serve-and-volley player per se. A booming forehand to go with his strong serve are Isner’s weapons and he obviously needs a racquet which supports those aspects of his game.

In the early part of his career, Isner used the Prince 03 Speedport White racquet. Prince offered a variety of other tennis racquets in 2011 and while Isner was initially reluctant to make any changes as most professional tennis players are, he took a liking to the EXO3 Black 100.

Isner prefers racquets which are lighter in weight, allowing him a better chance of swinging it, and his current model weighs just 315.8 grams (to give a context here, Nishikori’s racquet weighs about 11 grams more than Isner’s).

However, in more recent times, Isner has changed things around again and has a new racquet…

So, Which is John Isner’s Racquet?

John Isner’s current tennis racquet is the Prince Textreme Warrior 100, which he adopted after having played with the EXO3 Black 100 for many years.

Let’s talk about the specifications of the Prince Textreme Warrior 100. Its technical specifications are mentioned below.

  • Head Size: 100 sq. in./645.16 sq. cm.
  • Length: 27in/68.58cm
  • Strung Weight: 11.14oz/315.81g
  • Balance: 12.7in/32.26cm/6 pts HL
  • String Tension: 50-60 pounds

Also, Isner strings his Prince Textreme Warrior 100 with Tecnifibre Red Code while using a grip size of four and 5/8. With Isner not much of a volleyer, this racquet is suited for that kind of play; also a factor if you are looking to go ahead with this tennis racquet.

As a result, it’s also fair to conclude, this isn’t a racquet to be used by doubles players where net play remains the key.
