I can't see any reason to deal prospects for a hitter, not given what the budget is, and not given who is on the MLB roster, AAA roster, and AA roster. Now, pitching? I could maybe, maybe, see that. But, man, RPs especially are so hard to predict.
They aren't dealing for a catcher, and Farmer is easy to replace with Lee if you want. I just don't see how they could possibly deal for a hitter. As said above, LAST YEAR? Dealing for a hitter made a TON of sense....but nope. I'm guessing they add zero budget at the deadline, and the budget drops again next off season.
