You can always change it. But it's always important when things go bad that you don't get away from your plan and get scatterbrained. I pitch lefthanded batters a certain way, with the exception of three, and I don't vary from that. Unless I face a guy like Jim Edmonds five or six times and the approach I'm taking is not working, then I'll change. I don't change just because in one at-bat, Jim Edmonds hits a double off me.
Lefties have a hard time with a ball down and away.
I'm going to pitch them down and away. And until they all start driving the ball to left field off me, I'm going to keep doing it. So now you have to alter your game plan. And it's uncomfortable. My comfort zone is over that outside corner to a lefty.
