“It’s just simple: just keep fighting and keep believing, try not to show weakness out there!”
Started playing tennis seriously at age 11.
Isner is considered one of the best servers of the ATP World Tour. "Returning a serve like mine is like trying to hit a 100 mph fastball. If you don’t play tennis for a living, you will have a hard time."
Turned pro in the summer of 2007.
"When I was 18 I was able to vote and did not vote. I was very disappointed in myself. I didn't get into politics until after college."
Played the longest professional tennis match in history, defeating Nicolas Mahut in a total of 11 hours and 5 minutes of play over the course of three days at the 2010 Wimbledon Championships.
"I’ve always considered myself a team player even though I’m in an individual sport.
Four years in North Carolina high school and four years at the University of Georgia. When you’re playing for someone other than yourself, I think it makes it a lot more fun."
"I don’t consider myself a big spender, but I spend on food."
Isner has an extremely powerful and consistent serve, thanks in part to his 6 ft 10-in height which makes him the 3rd tallest player on tour behind Ivo Karlović and Reilly Opelka. "Being so big, I would have to be some sort of scary-like, villain-type of person."
Achieved his career-high singles ranking of world No. 9 in April 2012.
"I played my best tennis against Roger Federer at 2012 Davis Cup; probably because he's my favorite player. I am very close with all the American guys. Outside of that, I feel like I am close with pretty much everyone. All the South American guys, especially the Argentineans, are super nice. I think I get on with most people pretty well."
At 2012 French Open John also played the 10th-longest singles match, a 5-hour 41-minute encounter in the 2nd round. "My clay results in my career aren’t indicative of how good I can be on that surface. I beat Roger on clay. I took Djokovic to five on clay. I took Rafa to five on clay. Those are the best three in the world on that surface. So it’s something that I’m not shying away from."
In 2013, he became the 18th player to serve more than 5,000 aces on the ATP World Tour.
Currently has 10th-most aces in the history of ATP, having served more than 7,300 aces. "Things coming along now for American tennis are pretty nice."
"I enjoy the competition, but I enjoy the practice week as well."
"I’ve sort of always pulled for the heels, like the bad guys. So I think if I were a pro wrestler, first I’d need to bulk up, and second I’ll need to get sort of a bad-boy persona."
Going from any surface to hard court is a pretty easy adjustment. It's going from hard court to clay or grass that takes a little bit.
"Tennis players are pretty much used to changing conditions and time changes and what not."
