This sounds more to me like Dusty is just being cautious.

"I just thought he needed some time to get loose, get going. Some power pitchers are like that, and he's been like that the last couple games. Down the stretch, three through six, he's been pretty powerful in terms of velocity and stuff. And today, he had trouble getting to that point, trouble getting loose. All I could tell is that he wasn't as crisp compared to the last two starts that I had him, I don't know if that radar gun is right in left-center … some of the pitches he threw according to that gun were 87 to 91 (m.p.h.). A couple times he hit 95. But it just wasn't the same consistent fastball, the same consistent life we saw the two previous starts."
Wood got a visit from assistant athletic trainer Ed Halbur after the Griffey homer, but he stayed in to retire the next two batters.
When Wood came to the dugout after the third inning, he began shaking his right arm, according to Baker. "I knew we better get him out of there, He said it just didn't feel right. He warmed up great, Then in that one inning, he started feeling something. He wanted to stay in the game, certainly. Whether he was fine or not, that's a question. We don't want this to develop into anything real significant."
"Obviously, we looked and saw his velocity was a little bit down tonight from what it had been in the past," head trainer Mark O'Neal said. "When Ed went out there with Larry, Kerry denied symptoms. When he came in he was telling us that he was a little tight and we just didn't want to take any chances. So we pulled him from the game.
Wood threw 66 pitches, 41 for strikes. He gave up solo homers in each of his innings to Felipe Lopez, Adam Dunn and Ken Griffey Jr. respectively. [/url]
