An interesting article about Rich Hill today in the Sun-Times. 

His states that his problem this year has not been mental, but it's physical.

Left-hander Rich Hill continues to battle control problems at Class A Daytona, but he insists his problems aren't mental and says he doesn't feel forgotten after the Cubs traded for right-hander Rich Harden.

Hill told the Boston Globe his command problems have nothing to do with ''Steve Blass Disease,'' the mysterious and sudden inability to throw strikes.

''I don't even know what Steve Blass Disease is,'' said Hill, who was demoted to Class AAA Iowa in early May before being sent to the Cubs' training facility in Mesa, Ariz., in June when the problems persisted.

''I hurt my back. You can ask anyone who's ever played the game that when you suffer an injury, especially a pitcher, it throws your mechanics off. That's what happened to me. I don't have anything structurally wrong with my back, but I've had back spasms and I've had to do my rehab and stretching. I'm much better.''

What is your take on this? And was the back issue known in Spring Training and the beginning of the season when the started poorly?
