T-Kep has the news. Hirsh, a 27-yr old RHP, was acquired from Colorado for a PTBNL and will report to Triple-A Scranton. Once the Astros top prospect, Hirsh was dealt to Colorado in the Jason Jennings trade a few years back. His numbers playing at altitude the last few years aren’t pretty, the move was made to add a little depth in the upper levels.
Update (6:10pm): Oh, and Brett Tomko was released.
