There's only certain things you can control. I know how hard I work, I know how I take care of myself, and those are the two things I can control. As far as injuries and wear and tear and stuff like that, it's going to happen.
Don't get me wrong: I wouldn't wish it on anyone. Even the word 'cancer' brings back the nausea and pain, the fear I felt, and the heartbreak I saw in my parents' faces. The smells that fill hospitals and the constant tired feeling that comes with treatment are also permanently stuck in my memory.
Once you make the majors, it's never a great feeling to go back to the minors - no matter what the circumstances.
No matter what you do in the offseason, you can't simulate putting spikes on and standing in the grass and being around your teammates. When you're around your teammates, you step it up a notch. It's just kind of instinctive you do that.
You still have to pitch the same game, execute your pitches as best you can. If the shadows end up helping you out, then great, but you can't really worry about that stuff.
