It would depend on how badly the team losing Fielder needed pitching and if the hit he'd take in batting average warrants that gain in pitching. Another consideration is that if the league were shallow enough, the dropped player could be valuable too. Again hard to say if the trade is fair without more info.

Cmon Bud NOW is the time to sack up and force feed an Olympic style drug testing program down Fehr's fat throat and save OUR game from these blatant cheaters!
