I think developing prospective #4 starters in order to trade them at the deadline is a defensible strategy. Maybe he catches on right away in the big leagues, or, maybe it takes him three years to figure it out. I don't see the O's giving a guy three years to figure out how to be a #4. You trade for that guy or find him on a field in Mexico (like Miguel Gonzalez). So, I'm not all upset about giving up Davies. Whether or not Parra is the right guy we will have to see.
