Impact: Petro has played in nine games this season and if he steps on the ice in one more it will count against his service time. This is the reason he was a healthy scratch on Saturday. Clearly the Blues don't know how to proceed, but they'll have to make a decision soon as they can't just keep him in the press box all season. It would behoove the club to let the talented young defenseman develop at the highest level, but things don't always shake out that easily. Stay tuned.
