The timing of this is mostly PR, coming on the heels of the trading of a very popular player, and the surrendering of two quality bullpen arms. Lets face it, competing in the coming weeks with this club against the loaded Cubs could get ugly. I'm sure management wanted fans at least getting a glimpse of what it hopes will be a cornerstone player. I would be shocked if Hader is not up here to start one game of the doubleheader in Chicago, and then pitch out of the pen or take the occasional start.
