IIRC, a sticking point of Miller's signing was that he had to be added to the 25 man roster by Opening Day. Thus, per their agreement, I don't think the Cubs have the option to place him on the DL. Does anyody have any word on Miller's velocity yet? I don't think there's anything on record. He, like Wood, has been pitching behind the scenes. We should learn more as he progresses in his rehab. I'd be willing to bet that he pitches a game or two in the Minors prior to his first Cubs' start.
