With Ubaldo Jimenez returning from the paternity list on Tuesday, the Orioles needed to clear a roster spot and opted to do so by DFA'ing Borbon. Borbon's primary value to the Orioles was as a left-handed outfielder, but Hyun-Soo Kim's return nullified his role almost entirely. Borbon will now be subject to waivers, but he could return to the Orioles' organization if he goes unclaimed.
