David DeJesus was a bust after being acquired by the Oakland A’s, but his departure made the trade a successful transaction.
In theory, a trade is supposed to help both teams. Often times, that is not the case, with winners and losers becoming evident with the gift of hindsight. Then, there are those trades that seemingly do not work out for either team, such as when the Oakland A’s acquired David DeJesus from the Kansas City Royals for Vin Mazzaro and Justin Marks.
