I don't see them moving Vlad off 1B again
The system has guys coming up likely to play SS/3B
He's finally playing a position decently (above averagely even) and doesn't have to become a DH. I'm sure the front office is absolutely thrilled.
And he's hitting like a beast. Some guys seem to lose focus on hitting when they move around defensively or struggle defensively. Vlad probably isn't like that but why take the risk.
Bottom line? I wouldn't mess with it.
