European Tour loses Madrid Masters from the calendar due to financial crisis and woes of sponsor Bankia "That course beat me up," Casey admitted at Castle Stuart near Inverness, where the Aberdeen Asset Management Scottish Open starts on Thursday. The shoulder's absolutely fine and I feel good physically and mentally, but I just wasn't hitting it the way I wanted to. In a way, though, this is an opportunity. For a long time I was just on autopilot, but now I'm doing a lot of learning about my swing. I'm also being incredibly thorough and not leaving any stone unturned. I'm addressing the mental side, the nutritional side, everything I do on and off the course. Yes, the shoulder has damaged my golf, but I'm addressing all these other points now because I want to get to a whole new level. Casey, now down at 72nd in the rankings, spent two months out following his accident in Colorado on Christmas Eve and decided to take more time off last month even though it meant missing the US Open. The Ryder Cup star will be at Royal Lytham for the Open next week, however, and having already made a trip back to the course on which he won the English amateur title in 2000 he is warning what a tough week is in store there. "To me it was a classic course - make your score going out and hang on for dear life coming in," he said. Now, with the changes they've made, we hang on for dear life out and back. The sixth hole has changed from a par five to a par four and a total of 181 yards has been added since the 2001 Open. Former winner Mark O'Meara, 55, out of action since March with a rib injury, has withdrawn from next week's Royal Lytham tournament.
