After Marlon Byrd saw Carlos Marmol throw a batting practice session recently, he pulled the young Cubs closer aside. Byrd could tell what Marmol was throwing.
"I fixed it," Marmol said Tuesday. "It's not a good thing. I know what I have to do."
Hitters and pitchers usually keep to themselves, but Byrd, the new guy in the clubhouse, is doing what he can to help.
