Every week or so I find myself looking at Edouard Renaud and Cisco Argente and end up drooling all over my keyboard, but I just can't fit them into my line-up well enough to justify a trade...Renaud would only be hitting against lefties for me. Argente would start against righties, but he would be kicking another great infielder to the bench.
You should think about training Argente at 2nd or 3rd to boost his trade value, since you're not trying to win anyways. If he was fully trained at 3B right now I'd bite and have him start over Prazeres Matos, but I can't afford a black hole on defense in the middle of a playoff run.
