I don't think its going to happen yet. First of all, there are only 2 lefties in the pen, him and Wood. Wood seems to be viewed as the '6th starter' so if Richard is DFA'd and a starter goes down, we have no lefties in the pen. For whatever reason, managers all feel compelled to have lefties in the pen even if that lefty is bad and can't get lefties out. As far as Iowa goes, Concepcion and Zastryzny are options but neither are on the 40 man. Giovanni Soto is on the 40 man but isn't exactly lighting it up.
