Hirsh alone makes this trade worthwhile for the Rockies. 6-8, 245 pound flamethrower with good command of a 97 mph fastball but has the ability to sink it and generate groundballs with it.
Houston fans hate this trade today. They were hoping to have Hirsh be their firm #2 to Oswalt for the next five years.
I know Colorado fans think management is being cheap, but the current state of the market in baseball is outrageous. Due to the market conditions, the Rockies had to take a chance to get better next year.
Jason Jennings types are a dime a dozen in baseball. Jason Hirsh type talents are not.
