Re: 9/22/13 Reds @ Pirates
Ludwick has been mostly awful overall since he came back from the DL.
Let's not act like he's "must start" producing right now. Until he proves otherwise, he's just another guy that can be moved pretty interchangeably in and out of the line-up. At this point, giving him continued rest is probably the best bet to turn him into something more than that. And considering that he normally hits righties and lefties pretty equally, sitting him against a lefty makes just as much sense as anything.
