My backhand is definitely a lot more solid and consistent. There were times when I couldn't hit it into the ocean.

I still don't believe I won the U.S. Open. It's so far-fetched for me.

Umpiring, the only job in the world where you can screw up on a daily basis and still have one!

I don't know that I'll ever be the guy who needs to go to a tournament to be seen and to spectate. I feel like I can accomplish spectating from home.

I do understand that when someone gives you a [expletive] load of money, you take that money. Someone like Larry Ellison wants to invest into his event and make it the biggest possible, and he gets stopped by the ATP. If you're a start-up, what would make you want to navigate through that and to go through that firing line? How can you step into tennis with any confidence? It's the stupidest thing I've ever heard of.

I used to, like, hit for a half hour and then go eat Cheetos the rest of the day, come out and drill forehands. Now I'm really trying to make it happen, being professional, really going for it, and I miss my Cheetos.

It's pretty high up there on the list. Being able to return a serve at that speed is one of the biggest things that separates the professionals from the recreational players.
