It (soreness) actually (felt) worse at the end. It got worse towards the end. You know, I got through, so that's the most important thing. That's what I'm most happy about. I knew that before I started I wasn't going to be able to play like I usually can, move freely. But, you know, that's where I had my mind set on. I knew that. I was just trying to get the best out of myself with the way that I physically can, and that's all I'm going to try to do.

First week? I was very happy to get through today. I mean, the next match will be tough, especially now. So, yeah, you know, we'll see. Hopefully it can get better. Hopefully I stay positive and things won't be too bad tomorrow. Because it wasn't physically too tough today. That's the positive thing about today's match.

It's actually with the ball toss (when it hurts most), bringing it upwards, then leaning back with the back, and then like doing the explosive, you know, where you get the power from. Lucky, I have pretty strong arms. I can sort of compensate a little bit like that. If I can't rotate or use my full body weight, which every other player normally does, you use your movement and your body to produce power in your strokes. But now I'm doing a lot just with my arm in a lot of positions. That's something that, you know, is probably not the perfect way to play tennis. But for me that's good enough now.

Physically, I feel extremely well, perhaps fitter than ever.

When I was younger I used to have little aches and pains but they always disappeared, ... fling.

You can wake me up now - these last four weeks in America have been incredible.
