Considering the relative value we were giving up I would rate this as an excellent deal. First the guaranteed return of just over 1/5 (compared to a little over 1/3 of the season remaining) of his remaining contract in savings is more than I would have guessed we'd pull off while still getting a prospect worth caring about much. I don't worry about trying to saving Attanasio's money too much in these sorts of deals, but I will acknowledge the value particularly if it can ensure the team breaks even on the season and doesn't have to go super cheap on other things again. Second and more importantly it is a talent with some serious potential. I have little interest in older flamethrower's who haven't learned control (Hellweg etc.). Between his relative inexperience pitching, already being in AA and the fact that he currently isn't wild I have more confidence he can develop into at least a useful player and possibly even an elite reliever. Consider that the Pirates had the 7th ranked farm system coming into the year by minorleagueball.com and he was their 21st best prospect. I will crudely assert that this is roughly comparable to a similar ranking on our most recent community list. Which would be guys like Demi, Knebel, and Taylor Williams. Yes that is excellent value. Between more buyers, a better player, and a lower salary similar prospect return for Parra could easily be a player comparable to the outside of our current top 10. Which if that is all Melvin got done would still be a pretty good deadline, keeping in mind that Cotts is the only other player who might bring some real prospect value that would need to be dealt right now. That doesn't mean I'm not hoping for more, but there is not sense in getting weak value for guys who don't need to be dealt right now.
