Yeah I'm not going to dismiss it out of hand, it certainly raised an eyebrow, but I suspect it was just logistics in one direction or the other.
A) The team has insisted up and down dating back to the winter that Brown is still a SP
B) Brown has looked great this spring, well above expectation, and continued to do so as he's been stretched out
C) We have at least one non roster invitee (Snider) that looks like he's worth giving that last bullpen spot to
The timing feels weird to pull the rip cord on Brown as a SP.
