My first U.S. Open main draw, it was a big stadium and I wasn't really used to it.

I think my biggest thing is learning when to hit which serve when, not doing the exact same thing over and over. Because O.K., great, it's 120 miles per hour, but they're standing right there, and they just block it back.

When I have a nice rhythm going, and I have my toss in the right spot, when everything is kind of working how it's supposed to be, I think it's just really easy, you know, and I don't have to overthink on it.
