My doctor asked me how many golf balls I had hit in my career. I'm lying there in bed calculating somewhere between four and five million golf balls I had hit to do that on my body.

Obviously it's my second senior event, and I'm tired obviously coming back from the British Open, from surgery, which was priority No. 1, did that successfully, and each week since the British Open I've felt in pretty good control of my golf game.

When I turned 50, I said to myself, well, if this is what it's like turning 50, I can't wait to turn 60 because I still felt very, very mentally and physically good, outside my back surgery.

The game of golf doesn't come rushing back to you. Last week I made a couple of fundamental mistakes that I probably wouldn't have made in the heat of the battle back when I was in my heyday, and those things have got to come back.
