There is a lot of pressure on tennis players like other sports that are singular like you're not on a team. When all the pressure rides on your shoulders, it can be a lot different. Team sports you share those moments with the teammates. You share the pressures. You share the wins. You share the losses. You have a coach that can change the course of matches. But in tennis you're out there by yourself. There are no caddies. There are no coaches. You do it alone in the arena and I think that ups the ante a little bit.

You need to look to make a cohesive calendar that makes sense and helps elongate the careers of your players as opposed to shorten them inadvertently.

There's plenty of anecdotal evidence that most champions are born into certain environments and encouraged early. Then, later on, they might get some assistance from their federations.

America has an interesting global role, don't we? It certainly seems to be changing. Our government right now has a softer hand than we've had in the past, but I still think that we're the global behemoth.

I am there to play tennis and represent the U.S., but I'm also aware that not everyone's going to be able to think that way.

When your four biggest tournaments all operate relatively independently, and the ATP and WTA tour operate independently, and you have Davis Cup and Fed Cup that operate independently, it makes it a tough message.

It's unfair to expect the USTA, just because they make this pot of money, to just snap their fingers and make champions. It's not simple, and anyone who thinks it is hasn't really looked underneath the hood to see how the engine works.
