Dunn said that Sunday night's flight home from Anaheim was tough, but he tried to stand up and move around as much as possible. His biggest issue with the defensive component currently removed is getting loose before each bat.
"I have to probably go two or three batters before I normally do just to go and get loose again," said Dunn, who added that laying down makes the pain worse and sitting down makes it stiff. "Other than that, it's pretty much the same.
"Again, I never had any back problems. I don't consider this a back problem really. But I don't know. I guess it just has to run its course."
