First of all, this is hilarious.
Now, I just heard the news, and this is a real bummer. There were some really high hopes for him, and as was already mentioned, it's the type of injury that can permanently affect a career. I still think the trade was a decent one, taking into account obviously that there was no way Cashman could have known that this would happen. I liked Montero as a hitter, I didn't see him ever becoming a truly outstanding hitter, which IMO you need to be if you're going to be a DH as your primary position. So, I don't think Cashman really wrongly pulled the trigger, and who knows maybe Piñeda comes back next year and still works out.
