I still feel it out there. I really felt it when I jammed it about four times. But it's just something that I have to work through.

I still feel it out there. It's just when I jam my foot off during matches. It's something you can't test before a match. So I'm just trying to build it up.

I'm not quite 100 percent, so it's nice to get through. I felt like I moved a lot better in the past. It's a little bit of confidence with pushing off the ankle. Tonight's match was a tough because Paul competes his heart out, especially on a hard court.

I was just struggling a little bit with my movement. Just felt a step slower, a bit sluggish out there.

It's nice to be through to another semifinal, another tough match, ... Every match gets tougher.
