Yeah, Chapman looks like toast at this point and Dipoto isn't going to complicate his roster like that. That be a Cashman move, not a dipoto one. It would attempt to address a couple of issues. That article is more aimed at shoring up their defense but their hitting against left handers is terrible as well. Reysnyder gets the heat but a bigger issue might be Cal. That right handed production is missing now.
I don't know what you can do about it at this point. You're not going to be able to be too choosy about a bat if anyone is available. You can let Raley hit lefties but I'm not sure that's the answer.
