"It was just a freak thing," Piniella said.
"I've been off the mound longer than most of the guys here," Wood said. "Once we get the chest issue out of the way -- I still feel it a little bit -- I'll be OK."
Wood will throw on the side again Wednesday, increasing his pitches then, and could have two to three more side sessions before he faces hitters. The other pitchers are expected to throw on the side one more time before they see hitters.
Piniella likes the prospect of Wood moving to the bullpen.
"He's got a ton of talent and great stuff," Piniella said. "According to our medical people and our trainers, they feel that throwing less pitches more often is just the tonic he needs. I like the idea myself."
However, when Wood does throw out of the 'pen, expect him to limit his pitch selection to fastball, sliders and changeups. He'll likely skip the curve. Wood can't wait to stand on the mound and face a batter.
"I think everybody here is [anxious], but I've been off the mound for a while now and it'd be nice to get some feedback from somebody else," Wood said.
Quote of the day: "I've always liked Lou. It's like everybody says -- Lou's a beautiful person. He's fun to be out with. But when he puts that uniform on, you better play baseball. It's difficult for managers today because of the guaranteed contracts. But believe me, it's not difficult for Lou. He'll be lenient to a point." -- WGN Radio broadcaster Ron Santo
