Vasquez at DH....ok, hear me out.
The down side is obvious. If something happened to Maldy we lose the DH. But honestly, how likely is that? Far less likely than Mancini or Diaz getting a hit. And even if that did happen, and the pitcher's spot comes up, we could just use our PH as needed, we have 4 of them. So, now not only are we talking about the minuscule chance that Maldy would have to be removed, it would only really matter if it occurred in the first 6 innings or so, so the probability is cut down another standard deviation.
It won't happen. It's fan stuff. But, it's just Monday so why not think outside the box (score).
