I think Bo was more than mentally prepared to be in the show, it's obvious on how well he's handled himself so far. Sometimes younger players who feel they're overdue for a call up go stale mentally. Vlad and especially Biggio being called up didn't help either. I guess management wanted him to get more reps defensively, combined with the fact that Galvis was still here probably contributed to the delay. I knew he'd be a lightning bolt when he got here, but not at this level so far. The kid has an extremely high baseball IQ.
