I haven't seen this mentioned on here, and I think it's worth bringing to the attention of the Cub nation:

Kerry Wood said the change in his mechanics may not be noticeable to most people when he eventually returns from the disabled list after incurring a muscle strain in his shoulder one month ago.

"You probably won't be able to tell the difference," Wood said Saturday after throwing 60 pitches in a bullpen session. "Maybe [it's] a little less violent and little more smooth. There are not any drastic changes in arm angle or anything like that. I'll just try to keep my line to the plate straight."

...

"That's what we were talking about before," manager Dusty Baker said. "He was putting a lot of pressure on his shoulder because of the way he threw for a long time. We were just talking about getting it right, and that will help his control too."

...

Wood said he has altered his mechanics before, only to revert to his old form.

"It's sunk in a little more this time,' he said. "I don't know why. [Saturday] I was really getting after it. I wasn't thinking about it a whole lot. ... It's sinking in. In four weeks of pitching and playing catch, you have time to work on those things."

Wood will take a couple of days off and have a regular side session when the Cubs return to Wrigley Field before deciding the next move, likely a simulated game. There is still no timetable for his return, but if he continues at his current pace, Wood should be back before the end of June.

It's worth reading the rest of it, too.
