The Brewers are in first place despite a tough schedule, and were a game away from the world series last year. It would take a Vlad Jr. type prospect to create a noticeable buzz. This is not like Corey Hart in 2004. Hiura is off to a good start, but not so phenomenal that he needs to be brought up. If in a month, his hitting makes this look like a slow start, and Shaw, Aguilar and Thames are still struggling, then it would be a good idea to bring him up. Otherwise, let him work in AAA for most of the rest of the season.
