Mylan WTT is known for introducing innovations of all avenues to tennis. From the multi-colored court to substitutions and timeouts, there’s something unique for everyone.

World No. 12 John Isner is no stranger to what the League brings to the table. On Sunday, the ATP’s top-ranked American returned to the Boston Lobsters for the fourth year, having previously suited up for the team in 2010-2012.

Tennis.com caught up with Isner, who responded to a series of questions related to the Mylan WTT novelties he has come to appreciate over the years.

Has there ever been a time in a match where you wanted to use a substitution, either for yourself or a peer?

Certainly! When I’ve seen a friend of mine try to serve for a match and not really close it out, he could use my serve in that scenario. At the same time, when it’s a critical return situation, it wouldn’t be bad to have someone like Novak Djokovic sub in for me.

What is your favorite color on the Mylan WTT court?

I like the blue. I’m more partial to red and black, but it’s not quite red on this court. It’s more brownish. The court is great and the Lobsters’ stadium is nice.

All kids 16 and under have the chance to receive autographs from players like yourself after Mylan WTT matches. Whose autograph did you look forward to getting when you were a kid?

You’ll probably laugh but I grew up watching a lot of fake wrestling. I would wait in line and get their autographs.

There is quite a difference between tournament and Mylan WTT environments. Do you prefer the more traditional approach of an event like Wimbledon, or the rock-n-roll vibe of Mylan WTT?

I like the Mylan WTT environments, as I think they’re most similar to college tennis. They remind me of playing at Georgia. I think they’re great as they get the crowd involved. I think in situations like tonight’s match, it’s good to have the music and people socializing. You don’t want it to be so rigid.

Hypothetically, if all tennis players had last names on the back of their shirts like in Mylan WTT and other professional sports, which player’s ‘jersey’, past or present, would you want to own?

Probably John McEnroe. I think it would be cool to have one of his throwback jerseys in black.
