Matt Cain makes startling revelation about his pitching arm

Milwaukee -- Matt Cain made a startling revelation about his right arm: He said he has not been able to extend it fully since high school and has learned to throw without full extension. The bone chips in his elbow, which will be removed in surgery Monday, have worsened the condition.

Cain provided a demonstration in the visiting clubhouse Wednesday at Miller Park. He extended his left arm fully, but his right arm goes only so far.

"I've never had full range of motion in my arm," he said. "I still won't after the surgery. It won't be good for my elbow."

Cain finally agreed to surgery because the pain would not allow him to pitch.

"I lost too much range of motion in my arm," he said. "I probably would have lost stuff, too. It was just time to do it."

The 29-year-old right-hander firmly denied that the bone chips caused his steadily rising ERA over the past several years, saying, "I don't believe that's right. A lot of it was making bad pitches and not executing them. I didn't have a problem (with the chips) until just before the All-Star break."

Cain said the bone chips bothered him mainly between starts, and he found a way to "manipulate" them out of harm's way. Now they have shifted in a way that he cannot maneuver them.

He is unsure if he will travel with the team after the surgery but promised to be there for home games, saying, "I'm going to try to keep these guys as loose as possible."
