For me, this may very well be the straw that broke the camel's back with Cashman's off-season. In addition to whiffing on most every viable starting pitcher on the market, Cashman overpaid for a lefty specialist (relative to this off-season) while other similarly talented arms were available. And now, to add insult to injury (or injury to insult, I suppose), Feliciano may be severely damaged goods. I am grateful for the system's depth in solid candidates for the bullpen - but the team should not be in this sort of position in mid-April.
Here's hoping that my pessimism is unfounded, and that rest and rehab will have Feliciano ready to go sometime soon.
